Explain what is short circuiting and overloading in an electric supply.

(N/A) Short circuiting is the connection between two points in a circuit across which the resistance is very low. As a result,most of the current bypasses part of the circuit and flows between these two points. Short circuiting occurs when the live wire comes in direct contact with the neutral wire,such that a zero-resistance path is provided to the current. The current then does not pass through the appliance,but a heavy current passes through the wires of the circuit.
Overloading: Every circuit is designed to carry a pre-determined amount of power. When the power demand in the circuit exceeds the pre-determined capacity,the circuit is said to be overloaded.
