Solution

The figure above shows the most common fuse arrangement in which the fuse wire is stretched between the two metallic terminals T1 and T2 in a porcelain holder. This holder fits into a porcelain socket having two metallic terminals to each of which the live wire of the circuit is connected.
A fuse must not be replaced with a copper wire because copper has very low resistivity and high melting point.

Concept: Fuses
