Solution

Dear student,

(1)In terms of voltage and current, $P = V I$
(2)In terms of current and resistance,
$P = V I F r o m o h m s l a w, V = I R T h e n P = I R \times I P = I^{2} R$
(3)In terms of voltage and resistance,
From ohms law
$V = I R T h e n P = V I P = \frac{V}{R} \times V P = \frac{V^{2}}{R}$

Regards.
