Question

a fuse wire has high resistance

Answer 1

A fuse wire is an electrical instrument used for reducing the damage of electrical appliances when a high current passses into the wire. A fuse wire should have more resistance and a low melting point. It is due to the following reasons; It should melt easily if a highcurrent passes.

Answer 2

A fuse wire has high resistance and low melting point because when the high current passing through the circuits a fuse will resist the high current and protected the other electric appliances being damaged.

• Fuse is an electrical device contains metals that are tin, copper, zinc, and lead.

• This device is used to protect valuable electrical components.

• Fuses will separate the circuit from the source when the current flow increases its limit.

• A fuse wire melts easily if a high current passes through the circuit.
