a.) A 75W light bulb draws a current of 0.80A. If the light bulb stays on for 3.0 hours, how much charge flows through the light bulb?

b.) An ac generator produces a voltage given by V= 283 sin188t. What is the peak voltage? What is the frequency? If the voltage supplied by the generator produces a rms current of 2.0A in a device in the circuit, what is the resistance of the device?
