(a)
Old incandescent lightbulbs have a purely resistive metal
filament, through which flows an alternating current. If an
incandescent bulb uses an average power
of 60.0 W when connected to a 60.0
Hz power source having a maximum voltage of 170
V, what is its resistance (in Ω)?

(b)
Another incandescent bulb, with an average power usage
of 120 W, is connected to the same AC power source, with
the same frequency and maximum voltage. What is its resistance
(in Ω)?
