List two characteristics of the material used in a fuse wire. Name the material it is made of . A fuse is always connected in series in an electric circuit. Justify this statement giving reason.

Text Solution

Verified by Experts

The material used in the fuse wire should have a low melting point and a low resistance. Generally, the fuse wire is thin, made of copper, aluminium, iron, etc., all tin-plated or lead- plated. If a fuse is connected in series, the fuse wire melts when a high current flows and the circuit is broken. If it is connected in parallel, even if the fuse melts, current flows the remaining part of the circuit . Thus, a fuse is always connected in series.
