NCERT Solutions for Class 6 Science Chapter 9 - Electricity and Circuits

1. Fill in the blanks:

(i) A device that is used to break an electric circuit is called ---.

(ii) An electric cell has --------- terminals.

Ans:

(i) A device that is used to break an electric circuit is called a switch. 

(ii) An electric cell has two terminals.

2. Mark ‘True’ or ‘False’ for the following statements:

(a) Electric current can flow through metal.

(b) Instead of metal wires, a jute string can be used to make a circuit.

(c) Electric current can pass through a sheet of thermocol.

Ans: 

(a) True

(b) False

(c) False

3. Explain why the bulb would not glow in the arrangement shown in Fig.

Ans: The bulb will not light since the circuit is broken due to the insulator in the middle.

4. Complete the drawing shown in Fig, to indicate where the free ends of the two wires should be joined to make the bulb glow.

Ans : 

5. What is the purpose of using an electric switch? Name some electrical gadgets that have switches built into them.

Ans: A switch is a basic device that completes or breaks a circuit in an electric circuit. Electric fans, electric irons, toasters, and other electric appliances need switches.

6. Would the bulb glow after completing the circuit shown in Fig in the Q.4 if instead of a safety pin we use an eraser?

Ans: No, because the eraser is an insulator.

7. Would the bulb glow in the circuit shown in Fig. in Question 04?

Ans: No, the bulb will not glow.

8. Using the “conduction tester” on an object it was found that the bulb begins to glow. Is that objected to by a conductor or an insulator? Explain.

Ans: Because electricity can only pass through a conductor and not through an insulator, that object is called a conductor. The bulb will not glow unless the thing is a conductor.

9. Why should an electrician use rubber gloves while repairing an electric switch at your home?

Ans: Rubber gloves are used as insulators. This prevents the electrician from being electrocuted. That is why, when repairing an electric switch, an electrician wears rubber gloves.

10. The handles of the tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber covers on them. Can you explain why?

Ans: Plastic and rubber are both poor electrical conductors. As a result, they protect from electric shock.

NCERT Class 6 Science Chapter 9 - Quick Overview of Detailed Structure of Topics

Class 6 Science Chapter Electricity And Circuits Question Answer: Important Points

• Electricity is a form of energy resulting from the existence of charged particles.

• Common sources include cells, batteries, and mains electricity.

• Electric Cell:

• Structure: An electric cell consists of a positive terminal (marked with a + sign) and a negative terminal (marked with a - sign).

• Function: It generates electric power by converting chemical energy into electrical energy.

• Electric Circuit: An electric circuit is a path through which electric current flows.

• Components include a power source (cell or battery), connecting wires, and a load (like a bulb or fan).

• Types:

• Closed Circuit: Allows the current to flow and the device to operate.

• Open Circuit: Stops the current from flowing so the device does not operate.

• Conductors: Materials that allow an electric current to flow through them easily (e.g., copper, aluminium).

• Insulators: Materials that do not allow electric current to flow through them (e.g., rubber, plastic).

• A switch is used to open or close an electric circuit, thereby controlling the flow of current.
