Car batteries are rated by the following two numbers: (1) cranking amps=current the battery can produce for 30.0 seconds while maintaining a terminal voltage of at least 7.2 V and (2) reserve capacity=number of minutes the battery can produce a 25-A current while maintaining a terminal voltage of at least 10.5 V. One particular battery is advertised as having 905 cranking amps and a 155-minute reserve capacity. Which of these two ratings represents the greater amount of energy delivered by the battery? a. he 155-minute reserve capacity b. 905 cranking amps
