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 75 0 W when connected to a 60 0 Hz power source having a maximum voltage of 170 V what is its resistance in Q Q b Another incandescent bulb with an average power usage of 100 W is connected to the same AC power source with the same frequency and maximum voltage What is its resistance in Q
