NEET 2003 Physics question

Fuse wire is a wire of

(1)high resistance and high melting point
(2)high resistance and low melting pointCorrect
(3)low resistance and low melting point
(4)low resistance and high melting point

Answer: (2)

Solution

A fuse protects a circuit by melting when the current exceeds a safe limit. Heat produced is : a high-resistance wire heats up quickly, and a low melting point makes it melt (break the circuit) at a small rise in
