Question

A fuse wire should have(a) low specific resistance and high melting point(b) low specific resistance and low melting point(c) high specific resistance and high melting point(d) high specific resistance and low melting point.

Answer 1

Answer:

Option D is the right answer.

Explanation:

Low melting point wire is used for safety because when a current with high magnitude pass through the wire, it will melt and gives protection from short circuit. Wire used is of high resistance because when a large current passes it will heat quickly and causes a rise in temperature around the fuse wire, and it will reach the melting point, burn and protect the circuits form damage.
