physical question what is the formular and answer for
finding the power in 8-ohm electric heater operated at 120v

P = IV = I^2(R) = V^2 / R
P is power, I is current, V is voltage and R is resistance

The problem gives us the resistance and the voltage, so
we use P = V^2 / R

P = 120^2 / 8
P = 14400 / 8
P = 1800 watts
