# How much power is produced if a voltage of 12 V is applied to a circuit with a resistance of 72 Omega?

Jan 16, 2016

Data:-
Voltage$= V = 12 V$
$R e s i s \tan c e = R = 72 \Omega$
Power=??
Sol:-

We know that:
$P o w e r = {V}^{2} / R$

$P o w e r = {\left(12\right)}^{2} / 72 = \frac{144}{72} = 2$

$P o w e r = 2$ Watt
