An electric car is being designed to have an average power output of 4,900 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 70 V. What would the current be when they are operating at 4,900 W?
A
(c) To be able to recharge the batteries in 1 h, how much power would have to be supplied to them?
W
