An all-electric car (not a hybrid) is designed to run from a bank of 12.0 V batteries with total energy storage of 1.90 x 107 J. (a) If the electric motor draws 8.20 kW as the car moves at a steady speed of 20.0 m/s, what is the current (in A) delivered to the motor? 683 A (b) How far (in km) can the car travel before it is "out of juice"? 46.34 km (c) What If? The headlights of the car each have a 65.0 W halogen bulb. If the car is driven with both headlights on, how much less will its range be (in m)? 740 x m
