To recharge a 12 V battery, a battery charger must move 4.4 × 10⁵ C of charge from the negative to the positive terminal. What amount of work is done by the battery charger?

Question

Quizplus · Accepted Answer

The work done by the battery charger is calculated using the formula W = V × Q, where V is the voltage (12 V) and Q is the charge (4.4 × 10^5 C). Therefore, W = 12 V × 4.4 × 10^5 C = 5.28 × 10^6 J, which rounds to 5.3 × 10^6 J.
