A 100-W light bulb is connected to a 120-V wall outlet. What current will be passing through the bulb? What
is the resistance of the light bulb’s wire? If you run the light bulb for 500 hours in a town where the electricity
cost is $0.08 per kWh, how much would it cost you?
10.) What rms current is needed to transmit 50 MW of power at 20 KV? What would the peak current in that
situation be? If the resistance of the power line is 2.5 Ohms, how much power would be dissipated in the
line?
