How much work is needed to recharge a dead 12 volt battery if it can hold 24,000 coulombs of charge?
Nathan is using a 110 volt AC Skilsaw which draws 13 amps. He operates it for 2 minutes while attempting to cut out some plywood shelving. Assuming he doesn't cut off his foot in the process, how much charge is moved, and how much work is done moving it?
