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.
An electric car drives 40 miles, depleting its battery of 10 kWh of energy. It is charged by plugging into an outlet that draws its power from a natural-gas-burning power plant that has an efficiency of 35%. How much primary energy in kWh of natural gas was used to provide the 10 kWh of energy for the car's battery? Provide your answer to 3 significant figures.
An electric train weighs 216 tons with passengers and cargo. How much energy in kWh is required to reach the velocity of 137 km/h from standstill?
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.
Joe Bruin owns a Nissan Leaf electric car, but he wants to make the car even more “green” by installing solar cells on top of his electric car. Plus, in the event of a zombie apocalypse, Joe would like to be able to use his solar car to escape the zombies even after the electricity grid goes down. Joe’s car weighs 3500 lbs, and when the sun is shining overhead, the solar cells generate a total of 1000 watts of...
3. How long can a 12V car battery supply 250A to a starter motor if the battery has 4x106 J of chemical energy that can be converted to electric energy?

1. What is the emf of a battery that increases the electric potential energy of 0.050 C of charge by 0.60 J as it moves from the negative to the positive terminal? 2 .A thermistor is a device whose resistance varies with temperature. At 20∘C a thermistor's resistance is 10.0 kΩ. When connected to a 1.2 V battery, the current through the thermistor increases by 20 μA as the temperature increases to 30∘C. What is the thermistor's resistance at this...
