SOLVED: 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 60 Ah:(a) What is the maximum current that can be supplied for 15 minutes?(b) If the current drawn from this battery in a day has the following pattern, how many days will it last?𝑖 = 40 𝑚𝐴 07: 30 − 08: 0020 𝑚𝐴 12: 00 − 13: 0080 𝑚𝐴 17: 30 − 18: 000 𝑂𝑡ℎ𝑒r
