Phone chargers step down AC voltage of 240V (depending on the country) to DC voltage of 5V.

Most transformerless design employed in phone chargers nowadays does not completely isolate the mains (240V) from the output (5V) because one of the output terminals is always referenced to one of the mains terminal, which is usually the neutral line but can be accidentally reversed when plugging.

In electronics design, the common terminal is called the ground so one of the output terminal is referenced to the ground. In this case, we make use of the neutral line. But Unfortunately most chargers have just two legs that is plugged to the mains supply. What this means is that if the plug is reversed, The reference point will change and part of the output will be the LIVE line and this can be very lethal if you mistakenly touch the mouth of your charger or any other exposed part.

Engineers have found a way of eliminating this reversal by making use of three terminals.. So the next time you want to get a charger, make sure you get the ones with three terminals, they are the safest. With this type, you can only plug it in one direction..... Don't say it is too big, value your life.
Below is an example of the 3 terminal chargers I'm talking about.

WHERE ARE YOUR OWN INVENTIONS? WHAT HAVE YOU MANUFACTURED? WHAT ARE YOUR ACHIEVEMENTS AS AN ELECT-ELECT ENGINEER?
DO YOU THINK IT'S BY CAMPUS PHYSICS AND ODE?

KINDLY REPLY MY QUESTION AND STOP BOTHERING ABOUT YOUR FIELD. DO YOU KNOW MORE THAN THE PHONE MANUFACTURERS PRODUCING THESE TWO TERMINAL CHARGERS?
CAN YOU SEE THE CHARGER IN THE ABOVE PICTURE, WHAT DOES IT LOOK LIKE?

Jamesbiodun:
you are very wrong stop posting fake info and misleading people, there is no much difference between two terminal charge and the three terminal, when you plug your appliance in the socket ,it wont affect anything, have you wire a house before? you need to go to technicians , go to site and learn how it works not what you read in the book. mtcheew

You think to graduate as an Electrical and Electronics Engineer all you need to do is solve ODEs and pass other abstract courses? You have no idea of what Engineering entails.

A phone charger is even too elementary for me to be dragging words with you who does not have an iota of knowledge on how these things are built and operate.

FYI I have designed and built quite a number of complex projects so I'm not talking abstract. Infact to graduate as an Electrical and Electronics Engineer, it is one of the requirements. And no project supervisor will accept a charger from you because it is too simple.

Now you keep asking whether i know better than them, you are talking trash. If i show you the circuit diagram of this chargers, can you even interpret it? I gave a simple and a little technical explanation of how it works and you that has no knowledge in electronics is questioning me.

I'm finding it hard to comprehend you saying that chargers with three terminals are the safest.

Lots of electrical devices have plugs and chargers that come with just two terminals, are you saying the manufacturers don't know what they were doing?

CAPSLOCKED:


LOL, IF YOU WERE SO GOOD, YOU WON'T BE HERE ARGUING CHARGERS. YOU'D BELONG WITH ANY OF THESE MANUFACTURERS OR EVEN HAVE YOUR OWN BRAND.
ABEG GO AND SLEEP, YOU DON'T KNOW WHAT YOU'RE SAYING.

Hhenryy:


I know all you do is jump from thread to thread to mock people and get cheap likes without any meaningful contribution. Who is arguing chargers? Were you not the one that instigated the Argument?

I HAVE ONE BIG IKEBE TO HELP YOU CALM DOWN BECAUSE THAT'S YOUR SPECIALTY. MAKE I DROP CONTACT?

Most of those household devices you see making use of 2 terminals usually have transformers inside for complete isolation..... But putting a transformer in a phone charger will make it bulky, that is why they don't use it.

I'm not saying two terminal chargers are not good, they are more portable but in terms of safety, the 3 terminal ones are better due to the aforementioned reason.

The guy must be playing
PUBG
Fortnite

How is Call of Duty sef, I might try that one out.

Yeah, my thoughts, PUBG is so fucking addictive, given that I'm in my mid 30s I still play a lot. How is Call of Duty sef, I might try that one out.

SO DO YOU MEAN THAT THE MANUFACTURERS OF CHARGERS WITH TWO TERMINALS ARE GOATS, AND YOU KNOW BETTER THAN THEM?
