A heater is rated at 1200 watts for a 120-volt source. If two heaters are connected in parallel across the 120-volt source, the total power in watts drawn from the source is

Question

Quizplus · Accepted Answer

Each heater is rated at 1200 watts when connected to a 120-volt source. When two heaters are connected in parallel, the total voltage across the two heaters remains at 120 volts. The current through each heater is halved because of the parallel connection, which means the power drawn by each heater is also halved. Therefore, each heater draws 600 watts (half of 1200 watts). When two heaters are connected in parallel, the total power drawn from the source is the sum of the power drawn by each heater, which is 600 watts + 600 watts = 1200 watts. Therefore, the correct choice is C.
