EASY VOLTAGE DROP PART 2 - WHERE ARE THE WATTS

This is part 2 of our video on simplifying voltage drop. We have been asked a few times to explain what happens to the Watts when a circuit experiences voltage drop, and so, in this video from Learn Electrics, we will go back to basics and look at what happens to the voltage in a circuit and just as important, especially for understanding, why these things happen.

When you get into the practical calculations it really does open your eyes up to the amount of potentially wasted power that could go on in a domestic dwelling! Thanks for the video excellent as ever.

Aha! Back to basics always reveals the answer. Thanks Dave.

Another great explanation, the simplified diagrams work very well.

hey i have an exam in a month can u do city and guilds past papers, and thank u u r way better than my teacher

[lylewatts]

Thanks for another great video and you make it easy to understand. Now where were you 45 years ago when I was an apprentice trying to learn this?

Dear Sir,

I would be very grateful if you could tell me which type of MCB is suitable for each of the following home appliances:
- Split air conditioner.
- Fridge.
Electric stove.
- the oven.
- microwave.
- dish washer.
- Washing machine.
Clothes dryer.

Thank you very much

sincerely
Khalid

Love the video as always however can you maybe slow down a teeny bit so i can keep up i had to stop n re e wind a few times lol. its gonna take me an hour to watch these 18.49 mins at this rate. cheers n thanks

At 16:28 How could the MCB ever affect voltage drop ? Not sure what that sentence means ? Does the MCB have a resistance ?

[matt]

Very good explanation! P.s. Is there any chance for part 3 with Motor instead of Kettle? 🙃

If the 11.5V AC drop is the limit and the voltage in your house goes up and down. Is CU voltage input always the baseline for max volt drop or is there also a max figure regardless of the voltage input at CU

Where is the calculation with 2.5 t/e cable.
