CHAPTER 12_ Electricity and Circuits
ncert textual questions
1. Fill in the Blanks:
a) A device that is used to break an electric circuit is called a __________.
b) An electric cell has _________ terminals.
a) Switch b) Two
2. Make ‘True’ or ‘False’ for the following statements.
a) Electric current can flow through metals.
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.
a) True b) False c) False
3. Explain why the bulb would not glow in the arrangement as shown in the figure.
A. An electric current cannot pass through objects such as plastic scales, tester holders, etc., because these objects are bad conductors of electricity.
It can be observed that one terminal of the bulb is connected to a tester holder. The current will not flow through the circuit. Hence, the bulb would not glow.
4. Complete the drawing shown in the figure to indicate where the free ends of the two wires should be joined to make the bulb glow.
A. The given circuit is not complete. To complete the circuit, the positive terminal of the cell should be connected to one end of the switch and the negative terminal of the bulb should be connected to the other end of the switch. The closed-circuit is:
5. What is the purpose of using an electric switch? Name some electrical gadgets that have switches built in them.
A. A switch is an electrical device that is used to complete or break an electrical circuit. If the switch is ‘ON’, then a current can flow through the circuit. However, if the switch is ‘OFF’, then the current cannot flow through the circuit. Electrical appliances such as table fans, electric lamps, washing machines, juicer and mixers, TV, radio, etc., have switches built into them.
6. Would the bulb glow after completing the circuit shown in the figure, if instead of a safety pin, we use an eraser?
A. Erasers are bad conductors of electricity. They do not conduct electricity. The circuit becomes an open circuit. Hence, the bulb will not glow if a safety pin is replaced with an eraser.
7. Would the bulb glow in the circuit shown in the figure?
A. The bulb will not glow. This is because the two terminals of the cell are connected to the single terminal of the bulb. This is equivalent to the bulb not being connected to the circuit at all. The two terminals of the bulb should be connected to the two terminals of the cell.
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.
A. When the two free ends of the ‘conduction tester’ are touched with an object, then the bulb of the tester would glow if the object conducts electricity. However, the bulb would not glow if the object does not conduct electricity. Since the bulb glows when the tester is touched with the object, the object must conduct electricity. Hence, the object is a conductor.
9. Why should an electrician use rubber gloves while repairing an electric switch at your house? Explain.
A. An electric switch is an electric appliance. It conducts electricity through its internal parts. When its internal parts are touched with bare hands, then it may cause an electric shock. Therefore, it should be touched with rubber gloves in hands because rubber cannot conduct electricity. Hence, electricians wear rubber gloves while repairing a switch or any other electrical appliance.
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?
A. Rubber is a bad conductor of electricity. It does not allow current to flow through it. Hence, handles of tools such as screwdrivers, pliers, etc., which are used by electricians for repair use rubber cover on them. This protects them from electric shocks.
