The power is 992 W.

Step-by-step explanation:

Power is the product of resistance and square of the current. It is also defined as the rate of doing electric work.

Power = I^2 / R

where I represents the current,

R represents resistance.

Given R = 14.4 ohm, V = 120 V.

By using the ohm's law, we can calculate the current I

I = V / R

= 120 / 14.4

I = 8.3 A.

Now Power = (8.3)^2
* 14.4

Power = 992 W.
