Explanation:
Detailed explanation-1: -A fuse is a device that works on the heating effect of electric current. It consists of a fuse wire which has low melting point. It is connected in series with the appliance in a circuit. Whenever there is high electric current, more heat will be produced and it leads to the melting of fuse wire.
Detailed explanation-2: -The answer is (d) heating effect of current.
Detailed explanation-3: -Magnitude and heating effect of current are responsible for the working of safety fuse. A fuse has a metal wire or strip with low melting point that melts when too much current flows through it. Melting of which depends on the amount of current passing through which causes heating effect.
