An electric car is designed to run off a bank of 12-V batteries with total energy storage of 3.0 × 10⁷ J.If the electric motor draws 5,400 W,what current will be delivered to the motor?

Question

Quizplus · Accepted Answer

The power (P) drawn by the motor is 5,400 W and the voltage (V) is 12 V. Using the formula P = IV, where I is the current, we can solve for I: I = P/V = 5,400 W / 12 V = 450 A.
