------------------------------------------------ If a 12-volt car battery circulated 500 coulombs around a circuit, how much energy did the battery supply?

a) 6,000 J
b) 6,000 V
c) 500 J
d) 500 V

The energy supplied by a 12-volt car battery that has circulated 500 coulombs of charge is calculated using the formula E = V × Q, resulting in 6,000 joules (J). Therefore, the correct answer is a) 6,000 J.

Explanation:

When calculating the energy supplied by a 12-volt car battery that has circulated 500 coulombs of charge round a circuit, we use the formula for electrical energy, which is:

Energy (E) = Voltage (V) × Charge (Q)

In this case, the voltage (V) is 12 volts, and the charge (Q) is 500 coulombs. Therefore, the energy supplied by the battery can be calculated as:

E = (12 volts) × (500 coulombs) = 6,000 joules (J)

Thus, the correct answer to the student's question is a) 6,000 J.
