1.	We can save the household wiring and devices by using fuses. Write any four points by appreciating the role of fuse.
Answer» 1. A wire with high resistance is connected in the house hold circuit such that the entire current from the mains must pass through this wire called fuse. 2. It has low melting point. 3. When the current exceeds certain limit the fuse wire heats up and melts. Then the circuit becomes open. Thus preventing all electrical appliances from damage due to over load. 4. It is available in low cost and protects all electrical appliances from damage due to over load. Hence the role of fuse wire is highly appreciable.
