## NCERT Solutions for Class 6 Science Chapter 12 Electricity and Circuits

Q1. Fill in the blanks :

Answer: (a) The switch is used to break an electric circuit.

(b) An electric cell has two .

Q2. Mark 'True' or 'False' for the following statements:

Answer: (a) True , electric current can flow through metals.

(b) False , a jute string is not a conductor of electricity.

(c) False , thermocol is not a conductor of electricity.

Answer: In the given arrangement shown in the figure above the bulb would not glow because the screw/ tester driver is made up of plastic and plastic is a poor conductor of electricity.

Answer: The completed figure is shown below:

Answer: The purpose of using an electric switch is to make electric circuit open or closed for a particular appliance.

Some electrical gadgets that have switches built into them are table fans, torchlights, etc.

Answer: No, the bulb will not glow as the eraser is an insulator so it does not allow the current to pass through it.

Answer: From the given figure, we can observe that the circuit is complete and closed therefore, there is a flow of current in the circuit hence the bulb will glow.

Answer: Yes, if the object is a good conductor of electricity then the current will flow through the tester and the bulb will glow.

Hence, the object is a conductor of electricity.

Answer: An electrician uses rubber gloves while repairing an electric switch because rubber is an insulator and during the work when current-carrying wires come in contact with the rubber gloves the electrician will not get an electric shock. So rubber gloves are used for protection.

Answer: Plastic or rubber is a good insulator that does not allow the current to pass through it. Hence, the covering of plastic or rubber is made so that electric current may not pass through these tools to the body of the electrician to harm them.
