Assertion : Fuse wire must have high resistance and low melting point.
Reason : Fuse is used for small current flow only.

Why the fuse wire should have high resistance and low melting point?

A fuse wire is a wire of Low resistance and high melting point.

(A): Fuse wire must have low resistivity and low melting point. (R): Fuse is used to protect a device connected in series to it from large currents.

A fuse wire should have high melting point.

The material used for fuse has low melting point.
