    Answer:

    1440 W

    Explanation:

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

    P=VI

    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:

    P=(120)(12)=1440 W
