Question

Derive an expression for power int ermsofI&R​

Answer 1

Answer:

Answer. Electric power is the rate at which energy is transferred to or from a part of an electric circuit. ... By Ohm's Law, V = IR, and so there are additional forms of the electric power formula for resistors. Power is measured in units of Watts (W), where a Watt is equal to a Joule per second (1 W = 1 J/s).
