# How much power is produced if a voltage of 5 V is applied to a circuit with a resistance of 45 Omega?

Jan 17, 2016

$P = \frac{5}{9}$ Watts
or
$P = 0.5555$ Watts

#### Explanation:

We know:

$P = {V}^{2} / R$

$P = {5}^{2} / 45$

$P = \frac{25}{45}$

$P = \frac{5}{9}$ Watts

You can end the answer here or

$P = 0.5555$ Watts
