# How much power is produced if a voltage of 6 V is applied to a circuit with a resistance of 12 Omega?

$3 \text{W}$

#### Explanation:

Power is given by:

$P = V \times I$

To get the current we use Ohm's Law:

$V = I R$

$\therefore I = \frac{V}{R} = \frac{6}{12} = 0.5 \text{A}$

$\therefore P = 6 \times 0.5 = 3 \text{W}$
