Question:

The 12-V automobile battery in Figure P1–13 has an output capacity of 100 ampere-hours (Ah) when connected to a head lamp that absorbs 200 watts of power. The car engine is not running and therefore not charging the battery.

Assume the battery voltage remains constant.

(a) Find the current supplied by the battery and determine how long can the battery power the headlight.

(b) A 100 W device is connected through the utility port.

How long can the battery power both the headlight and the device?AppendixLO1image text in transcribed
