Question

When an electric circuit operates, a buzzer makes a sound. What happens to the electric charges in this circuit?

The electric charges move from the energy source and are used up at the switch.

The electric charges move from the energy source and are used up at the buzzer.

The electric charges move from the buzzer through the energy source and back to the buzzer.

The electric charges move from the energy source through the buzzer and back to the energy source.

Answer 1

Answer: Option (d) is the correct answer.

Step-by-step explanation:

In an electric circuit, when we press the switch or button then the circuit becomes complete. Then first of all current starts to flow from the energy source which might be a battery or cell etc.

Then the current reaches to the buzzer and hence, it makes a sound. After that, the current moves towards the battery or cell by completing its path.

Thus, we can conclude that the electric charges move from the energy source through the buzzer and back to the energy source.

Answer 2

The best option for the answer of this question is D) The electric charges move from the energy source through the buzzer and back to the energy source.
