Donald Trump is a very useless man, he had his hands full with the US election, but he still tried to impede Dr. Ngozi Okonjo-Iweala bid to become WTO chairman.

Now that Joe Biden have defeated him in the US election, he is running from Pilar to post trying to overturn the result of the election and no longer have the leeway to block Dr. Ngozi Okonjo-Iweala, she is already about to be announced as the new WTO chairman.

In the same vain, anyone that is trying to stand in the way of us achieving out God given destiny, they shall stumbled and fall. Crisis shall befall their life that they will no longer have time to pursue our matter. And by the time they turn to focus on us again, we will have succeeded in achieving our God given destiny.

Don't let the Umudikes on this forum hear you o, they are yet to recover from Trump's loss. They prefered Trump and his South Korean candidate than their own Sister. I am sure most of them love Trump more than their own mother.

You are a ridiculous liar, Mueller never said he couldn't prove collusion because of obstruction. His report was in two parts,in the first part he focused on collusion and said he couldn't find any evidence of collusion, in the second part, he spoke of obstruction and simply said that the terms of guidelines given to him did not allow him to make any determination on obstruction.

I don't expect any Trump supporter to be intelligent enough to interpret the Mueller Report. Your brain can only accommodate whatever Trump tells you.

The whole Mueller report systematically listed the numerous ways the Trump campaign colluded with Russian agents and officials to help Trump win the election.

Mueller never said he couldn't find any evidence of collusion, that's a lie being sold by Trump and his cult worshippers. What Mueller said was that "the evidence was not sufficient to support criminal charges. Among other things, the
evidence was not sufficient to charge any Campaign official as an unregistered agent of
the Russian government or other Russian principal.
And our evidence about the June 9, 2016 meeting and WikiLeaks s releases
of hacked materials was not sufficient to charge a criminal campaign-finance violation. Further, the evidence was not sufficient to charge that any member of the Trump Campaign conspired with representatives of the Russian government to interfere in the 2016 election"

Saying you don't have sufficient evidence for a criminal charge is not the same as not having any evidence. The evidence might not be sufficient for a criminal charges but sufficient for a civil charge.

Besides Mueller complained of lies and non cooperation from Trump and his campaign.

Bluebyrd:
That many people actually still believe that the Trump campaign colluded with Russia to steal the 2016 elections after all these years just shows you how much damage the fake news media has done. Even Muller after his two year witch hunt couldn't find any collusion, he very clear that there was NO COLLUSION between the Trump campaign and Russia to steal the elections yet the fake news media have put out so much bullshit out to their listeners that many of them actually still believe this lie till this day.

Big lie.
Mueller never concluded that there was NO COLLUSION between the Trump campaign and Russia. What Mueller concluded was that he could not prove collusion Trump campaign and Russia because Trump was OBSTRUCTING JUSTICE. He refused to testify, he refused to released documents Mueller asked for and refused to allow his people to testify. Mueller also concluded he could be prosecuted once he leaves office.

Hope that solves your problem.

Can you help me with this project im working on?
It involves regeneration. My question is which motor is the most efficient for power regeneration? Im working on a project where a gearbox is involved and i want to convert that mechanical power to electrical power. From my analysis, the max power in the output shaft is about 30W at. 2400rpm. I heard dc motors have a very low efficiency in regeneration. As low as 10% at that speed (even the geared ones) This means i can bearly power an led. What are my other alternatives. Do you know their efficiencies in regeneration?

I have never attempted power regeneration, but I think it involves trying to recover some energy from system that acquired some potential or even kinetic energy. For example when a car is going down a slope, some of its potential energy is converted to electricity using gears and alternator.


You will require a generator or alternator rather than a motor. Generators perform the reverse of motors. Some motors can act as generators, but they end up being very inefficient, and this probably explains why you are getting very poor output of electricity.

I have thought of attempting such a project and it was a car alternator that came to my mind. The problem with car alternators is that you need high RPM to get sufficient power from them.

If you are really serious about the project, you might need to order low RPM generators from alibaba or aliexpress, the type they use for wind turbines. They are very efficient and can work with as low as 100 RPM (revolution per minute).

benalvino2:
Lol, they were literally saying Russia stole the election and Russia hacked it.

I am not talking about Facebook post.

Provide the link where it says Russia tampered with actual votes or rigged the US elections.

Timiofak:
Wait before i go through with this, let me confirm from you, did flynn lie to fbi yes or no ?

Watching the videos is a waste of time and bandwidth. It's just dialogues between fox and friends on what they think Comey said or did and the crimes they think Comey and Clinton commited. They forgot to add that Hillary went through 2 years of senate and FBI investigations and she was given a clean bill by Republican controlled senate.
Clinton had left government for 5 years and the Justice department is controlled by Trump's houseboy, Bill Bar while the Senate is still Republican controlled. So, why hasn't charges been filled against Hillary Clinton?

Now, watch out for Trump. The minute he looses immunity, you will see dozens of criminal charges brought against him by both the justice department and southern district of New York among others.

Tony021:
Did i forget to mention that i not a pro power electronics guy nor electrical guy for that matter. Was just giving my input. Cant help you much here. No vex.
But im sure whoever can help will need more details about the tv like model name and such..

Ok, all power supplies work on fairly standard principles, with minor differences here and there. I asked a friend and showed him the capacitor, he told me the capacitor is just a boost capacitor. I am guessing the capacitor is used to regulate voltage in place of a choke. He said the capacitor should not affect the power supply much and the tv should still power on. I changed the fuse, and it went bang with sparks. I have traced that the power IC is also burnt. That must the issue causing the short circuit. I intend taking the power supply panel to Oshodi tomorrow to get the power IC changed or buy a new power board altogether.

Timiofak:
They said he was set up ooo

He was set up to lie to the Vice President?

benalvino2:
How does it connect to Russia? And he wasn't even guilty he was forced to plead guilty

Who then does Ambassador Sergey Kislyak work for?

I know in Trump's world lying is a past time, but in the real world lying under oath is a a crime. It was the same crime Bill Clinton was impeached for.

basilico:
I'll wait for election petitions.What crime did Mike Flynn commit

For one he lied to the Vice President and the FBI about discussing Russian sanctions in calls with then-Russian Ambassador Sergey Kislyak prior to Trump’s inauguration.

Tony021:
I understand where you were coming from. You actually explained it many times and i agree.

Oya all you electrical engineers, prove yourself. I need you guys help. Just this morning, my generation blew out my TV. My wife heard a loud bang from the TV. When NEPA brought light a few mins ago, I put on tv and it did not come on. On opening the cover of the TV, I found the Fuse and capacitor blown. I could not make out the type and value of the capacitor. So you power engineers on this thread, help me with the type and value of the capacitor below, so I can go looking for it.

benalvino2:
Lmao. They also said Russia was behind brexit, they said Russia wants to steal french election fearing macron will lose, same thing in Germany.

I don't know who defends Russia more - Trump or benalvino2? Maybe you are one of the many Russian trolls in Nigeria or Ghana.

Hillary has been saying on tape that Russia stole the election and Trump is an illegitimate president. Not just her the media has been saying that. Hillary also said Biden should not concede no matter what.

Please give us the link to the tape of Hillary saying Russia stole the election.

Trump had been insinuating he would not accept defeat right down from 2016. Did that cause you to be angry at Trump? No you guys increase your admiration of him.

You are just wriggling like a worm that salt has been poured upon, twisting, turning and summersaulting without any forward movement

benalvino2:
I personal don't think it will be easy to change the outcome of this but that does not mean there is no fraud. I have been saying this from the start. No one should just accept it without fighting.

There is fraud because you think there is fraud? What kind of logic is that? Even Trump lawyers could not tell a judge that there was fraud.

For 3 years all you guys said was Russia stole the election.

No one ever said Russia stole the election, the allegation was that Russia interfered in the elections through misinformation campaigns and hacking the email of Hillary Clinton and key members of the Democratic party.

Nothing was proven but courts took cases or listen to cases. Now this time they are saying lets look at the things so we can show you where everything is... And they said nope.

Nothing was proven but many Trump associates and campaigns members were found guilty? Nothing was proven but many Russian companies and individuals were inducted?

This sort of things happen in Nigeria all the time. Since everything is now political even the court... It means nothing can be done right

So the courts is not political abi? FBI, CIA, justice department, the Press, The Republican party (RINOs), everyone except Trump is political.

Tony021:
Yes, induction is a function of voltage. But if you read further down in that article you will see that to increase the voltage produced you need to increase the magnetic field strength while keeping the speed constant. This involves more force. And force is related to current in electromagnetism by the relationship F=kti. Here power is increased

This therefore means, at constant power, if the magnetic field strength (force/current) was increased, the relative speed would be reduced and hence the voltage. (P=IpVp)

Summary
You were right theoretically about no power when talking about transformers but only in an open circuit situation where there is no resistance. voltage can still be computed
NsVp=NpVs

Also when current is passing because of either the resistance of the wire or load in general and hence power, these formulas apply
IsVs=IpVp
NsVp=NpVs
You're both right, one is just talking about open circuit and the other is talking about in a closed circuit situation

Correct me if im wrong

You are correct. Obviously you are an electrical that understand beyond what you cram in textbooks.

My main premise once again is transformers work on the principle of induction which is a function of voltage fluctuations. I have never argued that current in a closed or loaded circuit do not alternate or fluctuate. What I am trying to explain to electrical engineer Simplyleo is that the current fluctuations is because of voltage fluctuations and not vice versa. Voltage has an inverse relationship with current, so if voltage increases, current reduces to maintain the same constant which is power, which is the main reason electricity is transmitted with high voltage and then stepped down in your homes.

I am not an electrical engineer, so I might not know the complex mathematical equations, but I understand the practical hands on aspects, because I have built and designed small power circuits.

benalvino2:
So in what you posted, where does it say state governors and court can change election rules?

Article 1, Section 4 of the US constitution.

Zeinymira:
Every year Lola wishes Andre and the twins happy birthday. If you follow them on social media you will see that Andre and Aliona are close friends, they have many videos together. Anita and Paul Okoye never reciprocated. Aliona modelled for Tanco (Anita's brand) last year.
Peter first child is about eleven years, he uses social media. He would definitely come across Paul's vile posts.....this fight will eventually become generational.
You can call someone out without insultive words. And this person his your brother's wife, not GF. The disrespect is too much.

Don't mind them. People supporting Paul's childish rants are very negative people with negative energy. A matured man or woman would not insult other family members in front of their children, as it will always affect relationships between the children and poison family relationships in general.

Jonathan39:
The mother did want her and she insisted in entering the family. Paul and Jude saw that as an affront against their mom, thats is the problem. I pity the lady sha

Abeg explain what you mean by "she insisted in entering the family". You mean she proposed to Peter, gave Peter an engagement and wedding ring and then took her family to pay the bride price of Peter?

Or

You mean that when Peter came on his knees professing his undying and everlasting love, pleading for Lola to marry him, she should refused to prove to Paul and Jude that she did not "insist in entering the family"?

benalvino2:
The evidence is there already. There are states that were unconstitutional by changing election rules. The court or state governors can't change election rules. That alone is enough to get to discovery but the country is gone. At this point I think they should just sit back and watch how the next 4years unfold

You still get mouth to talk? I thought you have gone away quietly like all your other Trump cult colleagues on this forum. But then it's seems shame is missing from your vocabulary.

In the US, it's states that organise and makes rules for elections, but with oversight by the congress. Asking Trump's worshippers to know that is asking for too much.

This one na agama lizard no be alligator, if him see proper alligator, him go don take off, before he remember say him get bingo.

Timiofak:
Sir trumps lawyer, none have alleged fraud in court. And none as shown any evidence of anything in court. Not twitter oooo, Court,

i dare them to take those there rubbish YouTube and twitter videos to court.

"In other words, Plaintiffs ask this Court to disenfranchise almost seven million voters. This Court has been unable to find any case in which a plaintiff has sought such a drastic remedy in the contest of an election, in terms of the sheer volume of votes asked to be invalidated. One might expect that when seeking such a startling outcome, a plaintiff would come formidably armed with compelling legal arguments and factual proof of rampant corruption, such that this Court would have no option but to regrettably grant the proposed injunctive relief despite the impact it would have on such a large group of citizens.

That has not happened. Instead, this Court has been presented with strained legal arguments without merit and speculative accusations, unpled in the operative complaint and unsupported by evidence. In the United States of America, this cannot justify the disenfranchisement of a single voter, let alone all the voters of its sixth most populated state. Our people, laws, and institutions demand more. At bottom, Plaintiffs have failed to meet their burden to state a claim upon which relief may be granted. Therefore, I grant Defendants’ motions and dismiss Plaintiffs’ action with prejudice. "-

He should name Hunter Biden, I want to see some people burn

I would love to see Hunter Biden as special adviser to the president on Ukraine and Hunter Biden's wife as special adviser to the president on everything else.

I want to see Trump worshippers wail until their eyes dry out.

Simplyleo:
Oga, abeg I don taya. I can't imagine myself arguing something as rudimentary as this with an electrical engineer.

Pls you Google. But before then, look at the screenshot below. Anywhere you come across a discussion contrary to what I said, pls let me know.

For now, I don taya.

Since you said I should use Google, I will. Maybe you will understand what I am trying to say.

The main crux of my argument is that electromagnetic induction, which is the principle which transformers work is a function of voltage, EMF or Potential Difference, and current is a natural consequence of voltage. Voltage is stored up energy, current is the actual amount of that stored up energy that's being used.

You can have voltage without current, but it's impossible to have current without voltage.

abumeinben:
There's no step down from 415 to 220. 415V is same as 220V. One is three phase connection, the other is Single phase. The aboki just do one science project for one community exhibition.

Thank you jare. I have always wondered why when 2 of those nepa wires join together it gives 415v. I had thought it's 415v that enters the transformer.
So how many volts enters our local transformer before it is transformed to 220/415v, is it 11,000 v?

Simplyleo:
You need to tell me the value of the current associated with the 415 volt of course.

Honestly, if you read electrical engineering, pls go back and read your books again. Or simply use the internet. I'm really surprised that an electrical engineer is asking these questions.

First I am not an electrical engineer, I am only a hobbyist with some circuit design experience.

Secondly, I know electrical engineers in this forum understands exactly what I am talking about.

Simplyleo:
You need to tell me the value of the current associated with the 415 volt of course.

You see you are now going back to my assertion. Current depends on the voltage by the relationship P=IV. You need the voltage and power before you can determine current. Meanwhile, voltage is already known whether power is consumed or not.
Induction depends on voltage and not current.

Simplyleo:
When talking about voltage transformation,
both voltage and current are transformed, a true electrical engineer should know this. Infact, this is the simplest part when introducing transformer as a topic.

In simple term, a transformer stepping up voltage is also stepping down current simultaneously.

Same applies to a transformer stepping down voltage, it also automatically steps down current.

Abeg, e don do, I no fit shout.

Ok, Mr electrical engineer, answer this question. When a transformer steps down a 415 voltage to 220v in your local transformer, to what amps does the transformer step down the current?

Simplyleo:
Pls answer this simple question.

Why is voltage stepped up for transmission?

You may use Google.

Hint.

Power input to transformer is VI

Power output is also VI

Neglecting power loss, power input =power output. But output voltage is higher than input voltage. The only way this can make sense is that the output current is lower.

Note, power is not increased in transformers, infact, power is lost due to hysteresis and eddy current.

Still, check google.

I don't know why you are obsessed with power, we're are not talking about power, we are talking about voltage . It is the voltage component of electricity that allows us to step up or down. Alternating (changing) voltage induces electromagnetic flux in the primary coils which in turn induces voltage into the secondary coil.

It seems you don't understand the definition of current and voltage. You are stuck with the relationship between voltage and current which is power or p = IV

Even the screenshot you posted talked about transformers being used to step up voltage and not current. It is the consequence of stepping up voltage that causes current to reduce (power being constant) due to the relationship between voltage and current - P=IV.

Simplyleo:
You keep getting it twisted.

Ever heard of current transformers?

Even the normal transformers step current up or down. Infact, that is the most important reason for stepping up voltage for long distance transmission to minimize power loss.

When a transformer steps up voltage, the current automatically steps down and power is transmitted at lower current to reduce ohmic loss. Ohmic loss is given by P= I²r

What do you mean step down current? Current flowing through a wire depends on the power being supplied by the wire. If there is nothing connected to the the wire, the current is zero (except the power wasted due to the resistance of the wire itself).

Simplyleo:
Fixed.

Inverters do the reverse. That's DC to AC.

I have admitted my errors. I have been a electronics hobbyist for over 20 years, so I know I made an error in my initial post.
A simple arrangement of 4 diode called bridge rectifier is used to convert AC voltage to DC. This is not even technically a DC voltage. The bridge rectifier only inverts the negative part of the voltage and converts it to positive, it's still an alternating current. To get real DC voltage you need complicated circuits consisting of capacitors, inductors and transistors (mosfets) to really straighten the signal with very little AC ripple.

Kokaine:
that's what I see it doing. 11kv will burn everything I'm seeing there.

The transformer is even labelled 33kv and not even 11kv.
