why is a fuse usually made of tin or tin alloy
Answers
Answer:
Fuse wire is made of a tin-lead alloy and not copper because of the following reasons. They have high resistance due to high resistance the wire heats up quickly, when large current flows through it. They have low melting point which melts and breaks off the circuit if the current is larger than the safety limit.An electrical fuse is a safety device in the circuit that protects electrical systems by breaking the connection when a short circuit is occurring
Answer:
When a large amount of current enters into the circuit,the fuse wire should melt according to Joule law of heating and hence disconnect the circuit
So the fuse wire should be made of a metal wire with low melting point
Hence a fuse wire is made of tin or tin alloy as tin has low melting point
