Does the length of charging cable affect the speed of charging.... Is it inversely proportional to charging speed? The longer the cable the slower the speed, and the shorter the cable the faster the speed... And if it affect it, what causes it?

Ftc for the first time ever on this platform, where is my own. I heard they do give things. Seun and co where una dey

Using the resistivity equation, we can see that the longer the length, the higher the resistance and this will lead to I²R losses. But this is usually countered by increasing the cross-sectional area of the wire. This is done by increasing the number of strands of wire or increasing the thickness of the wire.

Theoretically, length has an effect but when we want to design it for practical purpose, we counter that effect by increasing the thickness of the wire or using multiple strands. So when next you are purchasing a charging cable, you don't have to worry about the length affecting the charging speed because it has been taken care of.

Yes you did

you still interested in the 'Pro G' stuff?

Thanks! So that what makes some cable original and some fake even if they are the same length -the number of wires in the cable right? Or the quality of wire used?

Yes
The resistivity of a wire is directly proportional to its length
Increasing it's length increases it's resistivity
And opposite of resistivity is conductivity
Hope i have cleared you

Na maybe in the next 3years

Like I said earlier, to counter the effect of length we increase the cross-sectional area but you know that will lead to more cost. Therefore to cut cost, the producers of those fakes reduce the thickness of the wire and also the number of strands. That's why most fake products are usually cheaper than the original.

Both.

What disturbs the flow of electricity in wires is called resistance.
One of the things that determine whether this resistance will be high or low in a wire is the length of the wire. Resistance is high for long wires and low for short wires.
But that's just one of the factors. There are other things that work together with the length of a wire to determine whether current will flow well or not.
Just imagine yourself on a journey trekking. When will your energy drop more? When you travel over 1km or 100km?

is this theory applicable to transmission of electricity from the power station?

Your dad did not waste the tuition fee he paid for you
Well done

You sound knowledgeable with your language register. Are you trying to gauge our understanding depth or seeking a ratification of your own knowledge ?

I'm just trying to learn more sir.

Damnnn niggarrrr

Grab my gadmnnn weed to read some dope shit and learn
After una don yarn finish

Una go also explain to me why my charger dey do super fast charging on my phone

Shebi na cord still cause that one

And why he be say our normal electricity transmission (nepa) nor dey follow this principle...

Puffing my weed while I wait for response

Whilst having a lengthy cord might be useful for when you want to keep using your device, it is in fact slowing down your charging progress. This is due to an increased amount of resistance being present – the longer the wire, the greater the resistance

Nope it doesn't, for normal cable we buy.
ie upto 3m

What affects is the type of cable.

Too negligible to be of significance for domestic phone cables we buy.

Your thinking High Voltage miles long cables, then yes.
The resistance does not increase significantly for those home cables

.Wetin concern me

Abeg who go fit buy me food

I don't know jare

Well, for Direct Current (DC) transmission, the concept of V = IR holds well. The voltage at the end of the cable is directly proportional to the current at the initial end and inversely proportional to the resistance of the wire.

Now the resistance of the wire is a function of the lenght of the wire (wore inside the cable) as well as the cross sectional area of the cable (wire inside the cable).

This implies that the longer the cable with constant cross sectional area, the higher the resistance and also the lower the voltage and current at the other end of the wire.

The common leght for phone USB cables is usually 1 meter. The cable are usually designed with adequate cross sectional area to conduct the current needed to drive the voltage that charges the phone at the other end.

If you intend to increase the legbt of this cable, then you must definitely increase the cross sectional area, otherwise you get a voltage and current drop at rhe phone end of the wire.

Yes, if you understand ELECTRICITY RELATIVITY.

The longer the length of a wire conveying an electric current, the lesser the electric charge passing through the wire. That’s why transformer are designed to boost the current.
