There are different types of fuse.
CARTILAGE FUSE
Used in appliances such as refrigerators, AC' s etc. The wire melts when voltage is increased.
BLADE TYPE FUSES
Used in automobile to prevent circuit overloads.
RESSETABLE FUSES

Good evening....
Here is your answer.....
Electric fuse .....
An electric fuse is a safety device which is used to limit the current in an electric circuit. The purpose of the 'fuse' is to safeguard the circuit and appliances connected to it from getting damaged due to excessive heating caused by the flow of a large amount of current.There is always a maximum limit of the current which can safely flow through a given circuit or a given appliance. When the current in the circuit
exceeds the specified maximum (safe) value due to (0 short circuit (touching of wires leads to short circuiting), (ii) overload (more
than one device/appliance connected to single socket), (ii) insulation break down, the wires may become overheated and this can even result in a fire. It is in such situations that the 'fuse' plays its role. When we use a proper, and correctly positioned, fuse wire in the circuit, the fuse wire is the first to melt down when it gets heated up. This happens when the current in the circuit become'close to, or more than, the specified safe limit of the circuit. As a result a 'break' is created in the circuit and current flow, through it, stops immediately. The appliances are, thus, saved from damages.
