NCERT Solutions for Class 6 Science Chapter 12 Electricity and Circuits
1. Fill in the blanks :
(a) A device that is used to break an electric circuit is called _______________.
Ans : Switch
(b) An electric cell has _______________ terminals.
Ans : Two
2. Mark ‘True’ or ‘False’ for following statements:
(a) Electric current can flow through metals.
Ans : True
(b) Instead of metal wires, a jute string can be used to make a circuit.
Ans : False
(c) Electric current can pass through a sheet of thermocol.
Ans : False
3. Explain why the bulb would not glow in the arrangement shown in Fig. 12.13.
Ans :
The bulb would not glow in the arrangement shown in the figure because the one end of the tester/screwdriver is made up of plastic which does not allow the electric current to flow through it.
4. Complete the drawing shown in Fig 12.14 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 :
The purpose of an electric switch is to complete or break the circuit. Electrical gadgets that have switches built into them are Fan, refrigerators, television, microwave oven, electric cookers.
6. Would the bulb glow after completing the circuit shown in Fig. 12.14 if instead of safety pin we use an eraser?
Ans :
No, since the eraser is an insulator so it does not allow the current to pass. Hence the bulb will not glow.
7. Would the bulb glow in the circuit shown in Fig. 12.15?
Ans :
As we can see in the figure that two terminals of the cell are connected to a single terminal of the bulb which is the same as the cell and bulb are not connected. The bulb will not glow in this situation.
8. Using the “conduction tester” on an object it was found that the bulb begins to glow. Is that object a conductor or an insulator? Explain.
Ans :
Yes, if the object is a good conductor of electricity then the current will pass through the conduction tester and the bulb will glow. Hence the object will be a conductor of electricity.
9. Why should an electrician use rubber gloves while repairing an electric switch at your home? Explain.
Ans :
An electrician uses rubber gloves while repairing an electric switch at your home because rubber gloves are insulators. This protects us from avoiding electric shocks. Our body is a good conductor of electricity and rubber is an insulator. During repairing work if the body comes in contact with the current carrying wire then there will not be any accident as rubber does not allow the passage of current through it. Hence electricians use rubber gloves while repairing an electric switch.
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 :
Tools like screwdrivers and pliers are used by electricians for repair work because plastic is an insulator and plastic handles to protect the electrician from electric shocks. The handles of the tools like screwdrivers and pliers used by electricians for repair have a covering of plastic or rubber so that electric current may not pass through these tools to the body of the electrician to harm him.
