Question:
what is overloading of an electric circuit ? state two conditions that can lead to overloading for a circuit . how can it be prevented ?
Answer:
◆ Overloading of electric circuit:-
The current in a circuit depends on the rating of the appliances connected to it. The choice of wires depends upon the maximum current estimated to pass through them. If the total power rating of the appliances exceeds this permitted limit, they tend to draw a large current. This is known as overloading.
◆ Two conditions that can lead to overloading for a circuit:-
1. The live wire and neutral wire come in direct contact
2. Too many appliances are connected to a single socket.
◆ It can be presented:-
1. Before the wires can overheat, the fuse or circuit breaker will open, shutting off the flow of current.
2. Move plug-in appliances to a circuit that is less-used Remember not to turn on too many things at once.
3.Reduce lighting loads by replacing incandescent or halogen light bulbs with energy-efficient LED (preferably) or CFL (fluorescent) bulbs.

Answer:
It will be the sum of the currents drawn by the devices and can be greater than what is safe , This condition is called an overload .
