Laptop batteries are rated in W⋅h, the product of the power (in W) that the battery can provide and the time (in h) that it can provide this power. For instance, a 50 W⋅h battery can provide 50 W for 1.0 h, 25 W for 2.0 h, and so on. A 10.8 V laptop battery is rated at 76 W⋅h. What is the total charge the battery can provide to the laptop before the battery is depleted?
The relationship between the potential and the electric potential energy is given by U=Vq.

Batteries are rated by their voltage, but also by the energy that they can provide. A typical D-cell battery has a voltage of 1.5 V, and is also rated at 15,000 mA•h—a product of current and time. a. How much charge can flow from the battery before is discharged? b. For how long could this battery power a 1.5 W flashlight bulb?
1. When running on its 11.4 V battery, a laptop computer uses 8.3 W. The computer can run on battery power for 5.0 h before the battery is depleted. A) What is the current delivered by the battery to the computer? B)How much energy, in joules, is this battery capable of supplying? C)How high off the ground could a 75 kg person be raised using the energy from this battery? 2. An electric eel develops a potential difference of 480...
The total charge a battery can supply is rated in mA·h, the product of the current and the time that the battery can provide this current. A battery rated at 1000 mA·h can supple a current of 1000 mA for 1.0 h, 500 mA for 2.0 h, and so on. (a) A typical AA rechargeable battery has a voltage of 1.2V and a rating of 1800 mA·h. For how long could this battery drive current through a long, thin wire...
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? (¢)
The capacity of a storage battery, such as those used in automobile electrical systems, is rated in ampere-hours (A⋅h). A 50 A⋅h battery can supply a current of 50 A for 1.0 h, or 25 A for 2.0 h, and so on. 1) What total energy can be supplied by a 12 V , 50 A⋅h battery if its internal resistance is negligible? Express your answer using two significant figures. 2) What volume (in liters) of gasoline has a total...
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...

The capacity of a storage battery, such as those used in automobile electrical systems, is rated in ampere-hours (A · h). A 50-A · h battery can supply a current of 50 A for 1.0 h, or 25 A for 2.0 h, and so on. Consider a 12.0-V battery that has an internal resistance of 0.26 Ω and a capacity of 55.8 A · h. The battery is charged by passing a 9-A current through it for 6.2 h. (a)...
