Explain what is short circuiting and overloading in an electric supply

1.	Explain what is short circuiting and overloading in an electric supply.
Answer» Solution :Short circuiting: Whenever live and neutral wires come in contact with each other, the INCIDENT is called short circuiting. In this case, resistance of a circuit decreases to a very small value. The decreasing of resistance increases the current. Due to this increased current, the wires get heated. This extreme heat may cause fire in the building. Overloading: Every supply has a capacity to beara maximum load, i.e., the power that can besupplied has a limit. Sometimes, the number of appliances which are switched on at the same time have power more than the capacity of the LINE. This is called overloading. In this situation, wires of the supply get heated due to extremely LARGE current flowing through them and the circuit may CATCH fire. To avoid this fire, we use an electric fuse in the circuit.
