13-3 Automobile storage batteries are rated in tens of their terminal voltage (12 V) and their
ampere-hour capacities. For a typical 12-V battery having a 115-A-h capacity, determine the
length of time this battery will light a 6-Wbulb..(Assume the battery voltage is constant at 12 V throughout the test, even though that is not true.) Determine the total energy stored in the battery before it is connected to the bulb. Determine the total amount of charge that has passed through the wires that connect the battery and the bulb.
