Define electric power. Give its $SI$ units and write its mathematical equation.

(N/A) Electric power is defined as the rate at which electrical energy is consumed or dissipated in an electric circuit.
Mathematically,it is expressed as:
$P = \frac{W}{t} = VI = I^2R = \frac{V^2}{R}$
Where:
$P$ = Electric power
$W$ = Work done or energy consumed
$t$ = Time taken
$V$ = Potential difference
$I$ = Current
$R$ = Resistance
The $SI$ unit of electric power is the watt $(W)$,which is equivalent to $1 \text{ joule/second}$ $(1 \text{ J/s})$.
