Answer» Solution :SHORT Circuitng. If sometimes a live wire TOUCHES neutral wire or earth wire, a large current flows through the circuit due to almost zero resistance of the circuit. This is called short-circuiting. To save the circuit from damage FEARED due to over-loading or short-circuiting, a fuse of proper rating is put in each circuit. Over-Loading. The supply wires as well as wires used in household wiring has a SPECIFIC rating. The rating of 15 A means that if a current upto 15 A is passed through circuit, there is no likely damaged feared to the circuit. But if a current more than maximum ALLOWED limit is passed, there may be excessive heating of the wires and it may damage the wiring due to excessive heating. |
