a 12 V accumulator battery has a 55 A-h storage capacity. what is the total electric...
It has charged a accumulator with an unknown electrical capacity with a electric potential difference of 99.73 V. And when the accumulator was connected in parallel to a 10.0 μF electrical capacity or to another uncharged accumulator, the electric potential difference in potential for each accumulator was 32.0 V. What is the electrical capacity of the first accumulator? p.s I cant understand too. but it is only.
What is the total amount of energy stored in a 12-V, 85-A h car battery when it is fully charged?
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...
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)...
3. A pure electric car is designed to operate with 12 V battery with a total energy of 2.00010? 5 stored when it is full. When the car moves with constant speed of 20.0 m/s lits electric motor spends 8.00 kw power. a) Find the current used b) Determine the distance you can travel with one charge distance by motor
A pure electric car is designed to operate with 12 V battery with a total energy of 2.00×10^7 J stored when it is full. When the car moves with constant speed of 20.0 m/s, its electric motor spends 8.00 kW power. a) Find the current used by motor. b) Determine the distance you can travel with one charge.
1) A particular 12 V car battery can send a total charge of 84 A h (ampere-hours) through a circuit, from one terminal to the other. (a) How many coulombs of charge does this represent? (Hint: current = ) (b) If this entire charge undergoes a change in electric potential of 12 V, how much energy is involved?
An electric car has a battery that can hold 19 kWh of energy. If the battery is designed to operate at 340 V, how many coulombs of charge would need to leave the battery at 340 V and return at 0 V to equal the stored energy of the battery? Assume that the voltages are constant.
