Electric Power

When it comes to electric power, “work done” refers to the ability of the circuit to transform electrical energy into something else, like heat, motion or sound. “Work done” can also refer to transforming some other form of energy into electrical energy, as in a battery, which converts chemical energy to electrical energy.

As power is work done per unit time, with a little bit of math we find that electric power is defined as voltage times current: P = V x I.
