Define the term electric power. Write an expression for it.

Explanation

Electric power
Electric power is defined as the rate of consumption of energy or simply the rate of doing work.
i.e., power [P] = Work done [W] / Time [T] …..[i]
The work done by current [I] when it flows in a potential [V] for time [t] can be given by
W = VIt ....[ii]
`rArr` Power, [P] = VIt/t=VI
`therefore` Electric power or P = VI
