The home electrical connection consists of ‘live’, ‘neutral’ and ‘earth’ wires. The ‘live’ and the‘neutral’ wires have potential difference of 220 V. The ‘earth’ is connected to ground. Due to a faultin the equipment or if the plastic coating on the ‘live’ and the ‘neutral’ wires gives a way the twowires come in contact with each other and a large current flows through it producing heat. If anyinflammable material (such as wood, cloth, plastic, etc.) exists around that place it can catch fire.Therefore a fuse wire is used as a precautionary measure.
- Name the two wires having potential difference of 220 V.
- What is short circuit?
- Write the function of a fuse.

What is short circuit?
Due to a fault in the equipment or if the plastic coating on the ‘live’ and the ‘neutral’ wiresgives away the two wires come in contact with each other and a large current flows through itproducing heat. This is known as short circuiting.
Write the function of a fuse.
Fuse wire protects circuits and appliances by stopping the flow of any excess electric current.
Nice
But some are not with solution
Please chack them
