Answer:
- A fuse is a necessary in a circuit because it prevents a large amount of current from flowing in a circuit.
A fuse consists of an alloy that has a low melting point fitted on a surface made of porcelain or glass. When the current in a circuit increases because of some fault, the wire becomes hot and melts, thus breaking the circuit before damage is done.
