A light bulb is connected to a 120.0-V wall socket. The currentin the bulb depends on the time t according to the relation I =(0.788 A) sin [(469 rad/s)t]. (a) What is the frequency of thealternating current? (b) Determine the resistance of the bulb'sfilament. (c) What is the average power delivered to the lightbulb?
