Answer

The fuse wire is stretched between the two metallic terminals T1 and T2 in a porcelain holder (since porcelain is an insulator of electricity). This holder fits into a porcelain socket having two metallic terminals to each of which the live wire of the circuit is connected. Thus the fuse wire gets connected in the live wire. The below diagram shows the fuse arrangement:

The use of fuse is to safeguard the circuit and the appliances connected in that circuit from being damaged. It works on the heating effect of current. A material of low melting point is used so that it may easily melt due to overheating when current in excess to the prescribed limit passes through it.
