A heater is rated to dissipate 1440 W when connected to a 120 V source. The current drawn by the device is

The current drawn by the heater is 12 A.

Explanation:

Given;

power dissipated by heater, P = 1440 W

Source voltage, V = 120 V

The electric power of the heater is given by;

P = IV

Where;

I is the current drawn by the heater

Make I the subject of the formular;

I = P / V

Substitute the given values and solve for the current "I";

I = 1440 / 120

I = 12 A

Therefore, the current drawn by the heater is 12 A.
