A light bulb is connected to a 120.0-V wall socket. The current in the bulb depends on the time t according to the relation 1 = (0.838 A) sin [(491 rad/s)t]. (a) What is the frequency of the alternating current? (b) Determine the resistance of the bulb's filament. (c) What is the average power delivered to the light bulb?
