An automotive battery is rated at 120 A-h. Thismeans that under certain test conditions it can output1 A at 12 V for 120 h (under other test conditions, thebattery may have other ratings).a. How much total energy is stored in the battery?b. If the headlights are left on overnight (8 h), howmuch energy will still be stored in the battery in themorning? (Assume a 150-W total power rating forboth headlights together.)
