Answer: Overloading occurs when:
Many appliances are connected to a sing ke socket.
Many appliances are switched on at the same time due to which excess of current flows into the circuit and excess current is utlised by the circuit.
Electric appliances should be earthed because:
In case the metallic body of an appliances comes in contact with the live wire, then the current from the metallic body flows through the earth wire which is a low resistance and hence prevents the user from getting electric shocks.
