What is overloading? When does it occur? How can overloading be avoided?

(1) When the current in the circuit exceeds, the load exceeds the specified limit and overloading occurs.

(2) If many electrical appliances of high power rating such as geyser, iron, air conditioner, etc, are switched on simultaneously overloading may occur.

(3) The effects of overloading can be avoided by connecting a fuse in series with the circuit.
