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.
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 is being designed to have an average power output of 4,600 W for 2 h before needing to be recharged. (Assume there is no wasted energy.) (a) How much energy would be stored in the charged batteries? (b) The batteries operate on 60 V. What would the current be when they are operating at 4,600 W?
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?
An electric car is being designed to have an average power output of 4,200 W for 2 h before needing to be recharged. (Assume there is no wasted energy.) (a) How much energy would be stored in the charged batteries? ____J (b) The batteries operate on 50 V. What would the current be when they are operating at 4,200 W? _____A (c) To be able to recharge the batteries in 1 h, how much power would have to be supplied...
A typical family-sized electric car delivers PP=109 horsepower from its electric motor, which is powered by a lithium-ion battery that stores EE=23 kWh when fully charged. The car has a driving range of dd=112 km on a single charge. When fully charged, the car’s battery has a potential difference of VV=399 V across its terminals. (a) How far can this car drive on xx=1 kJ of energy? (b) What current is delivered by the fully-charged battery?
