Explanation:

A flow of large amount of current in a circuit, beyond the permissible value of current, is called overloading. It occurs when many electrical appliances of high power rating such as a geyser, a heater , an oven, a motor, etc. are switched on simultaneously . This causes fire.There are two possible causes of overloading in an electrical circuit and they are:
