An all-electric car (not a hybrid) is designed to run from a bank of 12.0 V batteries with total energy storage of 2.10 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? A (b) How far (in km) can the car travel before it is "out of juice"? km (e) What If? The headlights of the car each have a 35.0 W halogen bulb. If the car is driven with both headlights on, how much less will its range be (in m)?

Electrical Power Generation

In an electric power generator, one type of energy is converted into electrical energy. Power-generating systems are simply a combination of potential or stored energy that is converted to provide kinetic energy, which, in turn, generates electrical energy for use in engines, lighting, heating, and other benefits of modern life.
