Question

A heater is rated at 1200 watts for a 120-volt source. 
The resistance of the heater is 10 ohms.

Quizplus · Accepted Answer

The resistance can be calculated using the formula R = V^2 / P, where V is voltage and P is power. For a 120-volt source and 1200 watts, R = 120^2 / 1200 = 12 ohms, not 10 ohms.
