what is an electric fuse? what material is selected for fuse wire
Answers
An electric fuse is basically a device which is used as a safety measure in electric circuit to maintain the voltage of current, avoid short circuits and also to prevent the damage to appliances. ..
The materials used in a fuse are, a thin copper wire and PVC
The fuse is a safety device which limits the amount of current flowing in the circuit .
The material of the electric fuse is made up of an alloy of lead and tin .
Details :
It is made up of a material which has low melting point.
This will overheat them and make them melt easily.
Thus the fuse can easily break the circuit and save it if there is any excess current flowing in the circuit.
Explanation
The fuse is generally made up of thin piece of wire so that it offers more resistance and it can melt easily.
Thus the fuse works in the heating effect of current.
H = I²Rt
H = heat .
I = Current .
R = resistance .
t = time
