A battery can be rated in ampere-hours or watt hours. The ampere hours can be obtained from the watt hours by dividing watt hours be a nominal voltage of 12 volts. If an automobile battery is rated at 20 ampere-hours,
(a) what is the maximum current that can be supplied for 15 minutes?
(b) how many days will it last if it is discharged at a rate of 2 mA?
(a) I = 20/0.25 = 80 amps.
(b) days = (20/0.002)/24 = 416.7 days.
