Question
In the following circuit connect a fuse that will protect the load if a current greater than 10A, which is the current rating of the load, flows through it.
Hint:
Fuse is a protective device used to disconnect the supply when the current flowing through it exceeds.
The correct answer is:
Fuse is a protective device used to disconnect the supply when the current flowing through it exceeds. It is a wire made up of a metal that has low melting point. High current heats and melts it, breaking the circuit.
Third circuit will connect a fuse that will protect the load if a current greater than 10A.
