Explained what is short circuiting in electrect supply |
|
Answer» Yy always right What amit Yy alwys rght Nancy yy are my best frmd Short circuiting: Short circuiting occurs when naked live and neutral wires touch each other. In such a case, the resistance of the circuit becomes very less. Now, according to Ohms law, current is inversely proportional to resistance. Thus, the lowering of resistance of the circuit raises the current to a significant amount. As a result, the wires become hot and a spark is caused by Joules heating effect of current. This situation is known as short circuiting. Overloading: A large amount of current is withdrawn from the circuit, when a large number of electrical appliances of high power-rating are switched on at the same time or connected in a single multi-plug. This situation is called overloading. When live wire come in contact with earth wire |
