What Is Voltage?

This electronics video tutorial provides a basic introduction into voltage. It defines voltage as the electromotive force or potential difference acting between two points. It the work done by a coulomb of charge as it flows from one point to another point.

I don't know why this doesn't have more views but thank you so much.

[alberoDiSpazio]

Very comprehensive for 11 minutes. Making note of the distinction between Conventional current and Electron current was important as well. Keep up the good work.

This guy needs to win a Nobel peace prize because he is amazing.

This man is my hope in PCM

[ahmadabdel]

thank you, you have helped me go through the first year and is helping me through the second

[arafatalihridoy]

one of the best teacher I have ever seen.

[tedlahm]

Wonderful video. Could we us AC to see the difference at some point?
DC is clearer, yes, but we need to see AC also. thank you.

Your voice and pronunciation Are very good

When batteries are in parallel, how can current increase without any change in voltage? I found this on a website.
In general when Batteries are connected in parallel, the voltage remains the same while the current gets divided between the two batteries and so the runtime will increase.

so in that example with the 23v and 12v could we assume that were charging something since its flowing from a higher voltage source to a lower voltage source

[garrywellman]

Why did you subtract A-B in the first example but B-A in the second? Is voltage always going to go from highest to lowest?

[tomjoad]

The resistor affects the voltage of the wire before it? Like if the source is 12V and it has a wire coming out that is 1 inch long and then a resistor and then on the other side of the resistor it's now 8V after the voltage loss, does the 1 inch wire before the resistor also only have 4V instead of 12V? That's weird, if so.

so when you have to convert From Kv to V you multiply the value by thousand and when you have Mv and you need to convert it to V you divide it by thousand

[macroscopes]

If voltage is the difference in voltage between 2 points, how come each point (A and B) have their own voltage? I mean which would be the other point to compare for each case? If anyone is kind enouth to reply this.. thanks in advance!

COULD YOU PLEASE MAKE SOME VIDEOS ON FEET MOSFET DIA TRAIC

[tomjoad]

What is CONVENTIONAL FLOW? If electrons make up all electricity in circuits? You say conventional flow is + to -, which is caused by what since electrons flow from - and + and electrons make up all currents in circuits.

[Steven-ogtu]

Every person describes it differently why is it so confusing

[gustavosh.]

If current flows towards positive then how in these examples it is flowing from higher potential to lower potential?
TIA

[Salamanca-joro]

5:02 why did you subtract 12 from 23 ? Instead of subtracting 23 from 12 ? So that the answer can be -11 ??
Since the formula fot delta V is VA-VB And not VB-VA??
Any one have an idea?

How do I get this video to play on a TMY Projector?
