Case-Based-II: An electric fuse is a safety device that prevents overloading of any electrical circuit. A fuse is always connected in the live wire and in series with the electrical circuit. Fuse wire is made from low-melting alloy of copper and tin. In urban areas, the conventional cut-out type fuses are being replaced by MCB. The maximum current which can be passed through a fuse without melting it is called its rating.
A Copper wire should not be used as a fuse wire because
a. copper has very high melting point
b. copper has very low resistance
c. copper is very expensive
d. both (a) and (b)
