Answers
Answer:
Fuse is a material used to prevent our electric devices from getting damaged and also help us to be safe from electric damages.
Explanation
Commonly used material are copper, zinc, aluminium. Fuse works on I^2 x R principle. The heat developed by excess current will melt the fuse wire. Eg. At full load your house/motor/ appliance draws a specific amount of current lets say 5Amps. So fuse wire is set to a bit higher value like 5.5/6/7 Amps. 5Amps is not selected because you need 5A for the appliance to work, at 5A the fuse will burn. So you select a value slightly higher than 5Amps. You want the fuse wire to melt above 5Amps so that your device is not damaged. In this way your appliance is protected.
