Often when electricity is used we come across electrical fires caused.

Answer the following questions related to the following terms:

1. When does short circuiting take place?

2. What happens to the resistance of the circuit during a short circuit?

3. What happens to the flow of electric current during a short circuit?

3. What is overloading?

4. How can the effects of overloading be avoided?

Answer:


(1) When the live wire and the neutral wire come in direct contact, short circuiting takes place.

(2) The resistance of the circuit decreases during a short circuit.

(3) The flow of current abruptly increases during a short circuit.

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


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