Textbook Question
Chapter 1, Problem 36CP
A battery can be rated in ampere-hours (Ah) or watt hours (Wh). The ampere hours can be obtained from the watt hours by dividing watt hours by a nominal voltage of 12 V. If an automobile battery is rated at 20 Ah:
- (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?
