QUESTION:

The total charge that an automobile battery can supply without being recharged is given in terms of ampere- hours. A typical 12-V battery has a rating of 60 ampere- hours (60 A for 1 h, 30 A for 2 h, and so on). Suppose that you forget to turn the headlights off in your parked automobile. If each of the two headlights draws 3 A, how long will it be before your battery is "dead"?
