Question

what is the role of fuse, used in series with any electrical appliance? Why should a fuse with defined rating not be replaced by one with a larger rating?​

Answer 1

Hi friend !!

An electric fuse is wire which is made of a material of high resistance and low melting point. Using an electric fuse prevents the flow of unduly high electric current and protects the appliances from the damage. Due to Joule heating, the fuse melts to break the electric circuit.

A fuse with defined rating should not be replaced by the one with a higher rating because a fuse wire works due to its low melting point which is due to its rating and if a fuse with higher rating is used than it might not melt and thus failing in its purpose of using it.

Hope it helps.!!❣️❣️
