Final answer:

The power drawn from a 120 V source with a current of 12 A is calculated using the formula P = IV, resulting in a power of 1440 watts.

Step-by-step explanation:

To calculate the power drawn from a source, you can use the formula P = IV, where P is the power in watts, I is the current in amperes, and V is the voltage in volts. Given that the current (I) is 12 A and the voltage (V) of the source is 120 V, the power can be calculated as follows:



P = I × V = 12 A × 120 V = 1440 W



So, the power drawn from the 120 V source is 1440 watts.

Answer:

1440 W

Step-by-step 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
