# How much power is produced if a voltage of 8 V is applied to a circuit with a resistance of 64 Omega?

Feb 8, 2016

$1 W$

#### Explanation:

Current equals Voltage divided by Resistance
$I = \frac{V}{R} = \frac{8 V}{64 \Omega} = \frac{1}{8} A$
$\textcolor{w h i t e}{\text{XXXXXXXXXXXXX")1 A"mp" = (1 V"olt")/(1 "Ohm}}$

Power equals Voltage times Current
$P = V \cdot I = 8 V \times \frac{1}{8} A = 1 W$
