Problem 33

Rating Car Batteries Car batteries are rated by the following two numbers: (1) cranking the battery can produce for 30.0 seconds while maintaining a terminal voltage of at least 7.2 V and (2) reserve of minutes the battery can produce a 25-Acurrent 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?
