5) A car battery charger supplies 10A at 14V to recharge a 12V car battery. The charger runs off the 120VAC power line. Assume there is no loss in the charger itself.

A) How much power does the charger draw from the AC line?


B) How much current does the charger draw from the AC line?


C) If the battery stores 80% of the electrical energy coming into it, how much energy does the battery gain if the charger is connected to it for 10 hours?


D) If electricity costs $0.13 per kilowatt-hour, how much does it cost to run the charger for 10 hours?
