Fuse (lead+tin) has high specific resistance than copper. But fuse resistance is lesser than load.

Fuse has low melting point of fuse wire which will be burn at high current through wire.

Fuse is connected in series with load so we consider current passing though it.

Aaishu said:   1 decade ago
Yes, lead is used in fuse because of low melting point & high resistance.

A fuse wire always should have high resistance and low melting point.

Tinned copper and other low melting wire used in fuse is it right ?
