#### Answer

10 A. $12 \Omega$.

#### Work Step by Step

First find the current that is drawn.
$$Electric \; power = (current) \times (voltage)$$
$$1200 W = (I)(120 V)$$
Solve for I = 10 A.
Second, find the toaster's resistance.
$$Current = \frac{voltage}{resistance}$$
Rearranging to solve for the resistance, we obtain
$$Resistance= \frac{voltage}{current}$$
Put the numbers in from this problem.
$$Resistance= \frac{120 V}{10 A} = 12 \Omega$$
