The battery on your car has a rating stated in ampere-hours that permits you to estimate the length of time a fully charged battery could deliver any particular current before discharge. Approximately how much energy is stored by a 50 A-hour 12-V battery? b) Assuming 100% efficient energy conversion, how much water stored behind a 30 m high hydroelectric dam would be required to charge the battery?
