Question

Three bulbs are connected in parallel. What would be the result if one bulb were to burn out?

1) The resistance of the circuit would increase
2) All the bulbs would go out
3) The amperage in the circuit would decrease
4) Both a and c are correct

Answer 1

In a parallel circuit, if one bulb burns out, the other bulbs will continue to work.

Step-by-step explanation:

When three bulbs are connected in parallel and one bulb burns out, the other two bulbs will continue to work. This is because in a parallel circuit, each bulb has its own individual pathway for the current to flow through. So, even if one bulb is not functioning, the current can still pass through the other bulbs and illuminate them.

The correct answer to the question is option 2) All the bulbs would go out. However, this answer is incorrect because when bulbs are connected in parallel, the failure of one bulb does not affect the functioning of the other bulbs.
