An electric car is designed to run off a bank of 14.0-V batteries with total energy storage of 3.00 × 10⁷ J.If the electric motor draws 7 000 W,what current will be delivered to the motor?

Question

Quizplus · Accepted Answer

The current can be calculated using the formula P = IV, where P is power, I is current, and V is voltage. Rearranging gives I = P/V. Substituting the given values, I = 7000 W / 14.0 V = 500 A.
