Assertion: Fuse wire must have high resig. tance and low melting point.

Reason: Fuse is used for small current flow only.

View answer and explanation

Correct option: C

If Assertion is true but Reason is false.

Option C is correct. A fuse wire must have high resistance to generate heat and a low melting point to break the circuit when the current exceeds a safe level. The reason is false because fuses are used for a range of current flows up to their rated value.
