Question

Explain the role of fuse in series with any electrical appliance in an electric circuit. Why should a fuse with defined rating for an electric circuit not be replaced by one with a larger rating?​

Answer 1

Answer:

It protects the appliance due to short-circuiting or over / loading as when current exceeds the limit for which the fuse is rated, it blows off and the appliance is disconnected from the electric supply, When a fuse with defined rating for a particular appliance is replaced by one with larger rating, it does not blow off and appliance is damaged due to large current passing through it
