Another analogy :

Drop a very big stone from 1m high = high intensity/big Amps

Drop a small stone from 100m high = high voltage/big Volts

Drop a very big stone from 100m high = don't stand under it ! 🤣Â

I think it was my dad who taught me to remember the formulas like this:

Women Are VirginsÂ Â Watts = Amps * Volts

Virgins Are RareÂ Â Â Volts = Amps * Resistance

As simple as that! And I never forgot it, even after 50 more years!

Yes.

The other important measure in a dc circuit is power measured in watts.

Power (watts) = Â *Â Intensity of Current (amps) * Electric Pressure (volts)

P = I * E

Although it is probably obvious and because I can no longer edit the post I thought I should correct the typo in the formula just in case.

Power (watts) =Â Intensity of Current (amps) * Electric Pressure (volts)

What some people suggest may help is to use the diagram below and simply cover the value you are looking for with a finger and the remaining is the required calculation.
