4. An incandescent lamp, rated at 100 W, gives a certain amount of light when placed across the 120 V ac power line. Would the amount of light increase, decrease or remain the same, when the lamp is placed across a 120 V dc power line? Explain your answer. 5. How long does it take the voltage to go from zero to maximum on a 60 Hz power line? 6. On a 60 Hz power line, what is the time duration of the positive portion of one complete cycle?
