Suppose your waffle iron is rated at 1.90 kW when connected to a 3.60 x 102 V source (a) What current does the waffle iron carry? (b) What is its resistance? Need Help? 8. -12 points SerCP11 17.P.044 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 9-V...
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?

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...

A 5 V battery is rated at 1,709 mAh. What is the battery's lifetime (in hours) if the output current is kept constant at 64 mA? An electric car has electric motors that dissipate a maximum 19 kW of power. When the car's battery can store 44 kWh of energy, what is the shortest time (in minutes) that a fully-charged battery will completely discharge?
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...
The total charge that an automobile battery can supply without being recharged is given in terms of ampere-hours. A typical 12-V battery has a rating of 60 ampere-hours (60 A for 1 h, 30 A for 2 h, and so on). Suppose that you forget to turn the headlights off in your parked automobile. If each of the two headlights draws 2.1 A, how long will it be before your battery is "dead"?
(8) A heavy-duty battery for a truck is rated n amp-hours. What is the amount of electrical energy that this battery can deliver? (10 pts)
What is the total amount of energy stored in a 12-V, 85-A h car battery when it is fully charged?
