Question

Batteries are rated in terms of ampere-hours (A · h). For example, a battery that can deliver a current of 3.0 A for 5.0 h is rated at 15 A · h. (a) What is the total energy, in kilowatt-hours, stored in a 12-V battery rated at 50 A · h? kWh (b) At $0.16 per kilowatt-hour, what is the value of the electricity that can be produced by this battery? ¢

Step 1

Given: Voltage (V) = 12 V, Rated power (P) = 50 Ah Total energy = Voltage x Rated power Total energy = 12 V x 50 Ah Total energy = 600 Wh To convert watt-hours to kilowatt-hours: 1 kWh = 1000 Wh Total energy in kilowatt-hours = 600 Wh / 1000 Total energy in Show more…
