a means to measuring the pieces of energy.


Current, and not voltage, is what that can kill in electrical accident.

Real Talk

It's important to learn about the basic SI units related to electrical power and energy. The current flowing through a conductor (e.g. a wire) is directly proportional to voltage, as expressed in Ohm's law: I=V/R (I=intensity or current, V=voltage, R=Resistance )
