The capacity of a storage battery, such as those used in automobile electrical systems, is rated in ampere-hours (a? h). a 50 a? h battery can supply a current of 50 afor 1.0 h, or 25 a for 2.0 h, and so on. a) what total energy can be supplied by a 13v , 60a? h battery if its internal resistance is negligible? answer= jb) what volume (in liters) of gasoline has a total heat of combustion equal to the energy obtained in part (a)? (see section 17.6; the density of gasoline is 90 kg/m 3.)answer= lc) if a generator with an average electrical power output of 0.45 kw is connected to the battery, how much time will be required for it to charge the battery fully? answer= h
