Question

What happens if we connect a fused bulb in an electric circuit?

• A. The bulb burns immediately.
• B. There is closed path for the flow of electricity.
• C. The bulb glows brightly.
• D. The bulb doesn't glow at all.

Answer 1

The correct option is D The bulb doesn't glow at all.

A bulb is said to be fused if its filament is burnt or blown. So when such bulb is connected in a circuit, the circuit remains open and the electricity doesn't flow through it as there is no closed path for it to flow.
