Which material is generally used in fuse wire?

Answer: Tin (Sn) and lead (Pb) are generally used in fuse wire. It is used in electrical fuses, which are safety devices that protect electrical circuits from damage. When too much current flows through the circuit, like during a short circuit, the fuse wire melts and breaks the connection. This stops the flow of electricity and prevents damage to appliances or even fire.

Complete Answer:

A Fuse wire is a crucial part of an electrical circuit. It helps prevent electrical devices from damage by excessive current ( referred to as overcurrent). If too much current passes through a circuit, the fuse wire melts and destroys the circuit. This stops the flow of electricity and protects the devices.

The most commonly used materials in fuse wire are tin (Sn), lead (Pb), or an alloy of tin and lead. The material is generally used in fuse wire with a low melting point and high resistance. In many cases, a special alloy called solder wire (made of about 63% tin and 37% lead is used. 

These metals are chosen because they melt quickly when too much current flows through them. This helps in breaking the circuit before any damage happens to electrical appliances. 

In simple words, fuse wire is usually made of a low melting point metal, like tin-lead alloy, so that it melts easily when there is too much electricity, which helps to protect our devices.
