Question

What is the power when a voltage of 120 volts drives a current of 3 amps through a device?

Answer 1

ANSWER

360 W

EXPLANATION

Given:

• Voltage, V = 120 V

,

• Current, I = 3 Amps

Find:

• The power, P

The power is given by,

$P=V\cdot I$

Substitute the known values and solve,

$P=120V\cdot3Amps=360W$

Hence, the power on the device is 360 W.
