A current of 12 A is drawn from a 120 V source. Calculate the power.

1440 W

Explanation:

The power drawn by a voltage source is the rate of energy consumed, and it can be written as:

where

V is the voltage

I is the current

P is the power

For the source in this problem we have:

I = 12 A is the current

V = 120 V is the voltage of the source

Solving for P, we find the power:

if they have a finite resultant
