Batteries are rated in terms of ampere-hours a middot h., Ask an Expert

Academics

Q. Batteries are rated in terms of ampere-hours (A · h). For example, a battery that can produce a current of 3.00 A for 5.00 h is rated at 15.00 A · h.

(a) What is the total energy stored in a 9.0-V battery rated at 49.0 A · h?

(b) At $0.0590 per kilowatt-hour, what is the value of the electricity produced by this battery? NOTE: Enter your response with hundredths precision.
