Question
What happens in the fuse which melts it to break the electrical circuit?
Answer: Option B
:
B
Fuseis a protective device used to disconnect the supply when the current flowingthroughit exceeds. It is a wire made up of ametal that has low melting point. High current heats and melts it, breaking the circuit.
Joule's heating is the phenomenon that takes place in the fuse which helps itto break the electrical circuit and hence prevents accidents.
