D) The material used for fuse has low melting point. OR
A fuse should be made of a material of low melting point.
Answers
Answer:
fuse is a safety device which helps when the current exceeds some limit in the circuit. It can be made up of a metal wire or a strip. Without fuse, there is a chance of damage to electrical and electronic components.
Answer and Explanation:
High resistance of fuse means it has high opposition to flow of electrical current.
This releases heat energy with the increase in temperature of fuse wire.
At some safety point set, the fuse reaches melting point and the connection breaks.
Low melting point is necessary so that the fuse wire melts first before there is any damage to other wires.
Answer:
Lead and silver.
Explanation:
I think this should be the answer.
or
A fuse is made up of a material of low melting point due to the Joule's Heating effect of electric current as it melts after an short circuit to protect the electrical appliances.
