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 stored in a 9.0 V battery rated at 51.0 A·h? kWh (b) At $0.0630 per kilowatt-hour, what is the value of the electricity produced by this battery?

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 51 A · h? (kWh) (b) At $0.12 per kilowatt-hour, what is the value of the electricity that can be produced by this battery? (¢)
battery that can deliver a cu (a) What is the total energy, in kilowatt-hours, stored in a 9-V battery rated at 47 A h? Batteries are rated in terms of ampere-hours (A h). For example, a rrent of 3.0 A for 5.0 h is rated at 15 A·h. kWh (b) At $0.19 per kilowatt-hour, what is the value of the electricity that can be produced by this battery?

Car batteries are often rated in amp-hours. This rating indicates the quantity of charge that can pass through the battery before the battery's chemical energy must be restored by the car's generator or some other source. The amp-hour unit is convenient for simple calculations. For example, a 60-amp-hour battery can supply a current of 1.0 A for 60 h (or 60 A for 1.0 h) before going dead. Find the energy stored in the following. (a) a 54 A-h, 14...

Problem 2: Pedal Power
Many villages in the developing world lack access to electricity.
One proposed solution is the ‘Free Electric’ bicycle, which is a
stationary bike hooked up to a generator and battery. Pedaling the
bike powers the generator, which creates electricity that is stored
in the battery. The inventor claims that 1 hour on the bike can
produce a whole day of electricity. Let’s put it to the test!
Assume the following: The human body is 25%...

Duke Energy manufactures and distributes electricity to customers in the United States and Latin America. Duke recently purchased Cinergy Corporation, which has generating facilities and energy customers in Indiana, Kentucky, and Ohio. For these customers Cin- ergy has been spending $725 to $750 million each year for the fuel needed to operate its coal-fired and gas-fired power plants; 92% to 95% of the fuel used is coal. In this region, Duke Energy uses 10 coal-burning generating plants: five located inland...
