What total energy can be supplied by a 12 V, 60 A * h battery if its internal resistance is negligible?

The ability a storage battery, as used in automotive electrical systems, is in ampere-hours (A * h). A 50 A * h battery can supply a current of 50 V for 1.0 hours, or 25 V for 2.0 hours, and so on. What total energy can be supplied by a 12 V, 60 A * h if the battery internal resistance is negligible? What volume (in liters) of gasoline has a total combustion heat equal to that obtained in part (a)? (the density of gasoline is 900 kg / m ^ 3). If a generator with an average output power of 0.50kW is connected to the battery, how long will need to be fully charge the battery?

____________________________ Total energy supplied by a 12 V battery of 60 A * h = QV U = U = 60 * 3600 * 12 Total energy supplied by a 12 V battery of 60 A * h = U = 2.592 * 10 ^ 6 J time to fully charge the battery = T = Energy (U) / hour of energy needed to charge the battery fully = 2.592 * 10 ^ 6/0.5 * 10 ^ 3 The time needed to fully charge the battery = 5184 seconds Time to fully charge the battery = 1.44 hours or 1 hour 26 minutes 24 seconds __________________________________
