Batteries are rated in terms of ampere-hours (A · h). For example, a battery that can produce a current of 2.00 A for 3.00 h is rated at 6.00 A · h.
(a) What is the total energy, in kilowatt-hours, stored in a 12.0-V battery rated at 55.0 A · h?
(b) At $0.060 0 per kilowatt-hour, what is the value of the electricity produced by this battery?
