Question

An alarm clock has a resistance of 14,000 ohms and is plugged into a 120-volt outlet. How much power does the clock use?

Answer 1

Power used by the clock=1.03 W

Explanation:

resistance= 14000 ohm

voltage=120 V

The formula for the power is given by

$P=\frac{V^{2}}{R}$

P=(120)²/14000

P=1.03 W

Answer 2
