11. Will the bulb glow in the circuit shown in Fig. 12.6? Explain. 

seo images

                                                         Fig. 12.6

Ans: Since the switch is open, the bulb will not light, indicating that the circuit is disconnected.

12. An electric bulb is connected to a cell through a switch as shown in Fig. 12.7. When the switch is brought in ‘ON’ position, the bulb does not glow. What could be the possible reason/s for it? Mention any two of them. 

seo images

                                                Fig. 12.7

Ans: There might be a variety of causes for this: 

i. The cell is used. 

ii. The bulb has blown out. 

iii. Interconnections that aren't secure. 

iv. A breakage in one of the connecting wires.

13. A torch requires three cells. Show the arrangement of the cells, with a diagram, inside the torch so that the bulb glows. 

Ans: The bulb will be connected to the positive and negative terminals. The arrangement of the cells will be as follows:

14. When the chemicals in the electric cell are used up, the electric cell stops producing electricity. The electric cell is then replaced with a new one. In rechargeable batteries (such as the type used in mobile phones, cameras and inverters), they are used repeatedly. How? 

Ans: Secondary cells or storage cells can replenish rechargeable batteries by delivering current.

15. Paheli connected two bulbs to a cell, as shown in Fig. 12.8. She found that the filament of bulb B was broken. Will bulb A glow in this circuit? Give a reason. 

seo images

Ans: The bulb will not glow as the filament is broken, which makes the circuit incomplete.

16. Why do bulbs have two terminals? 

Ans:  In a bulb, the filament is a small thin wire attached to two terminals inside the circuit to allow electricity to flow through it.

17. Which of the following arrangements, A, B, C and D given in Fig. 12.9, should not be set up? Explain why. 

seo images

Ans:  Because Circuit A is an incomplete circuit, it is improper. The current will travel from the cell's negative terminal to the positive terminal, using all power and leaving no output.

18. A fused bulb does not glow. Why? 

Ans:  When a bulb's filament is broken, the bulb is said to have been fused, which means it won't light up because the filament is the bulb's major source of light. The circuit is not complete since the filament is damaged, and the bulb can not light.

19. Paheli wanted to glow a torch bulb using a cell. She could not get connecting wires, instead, she got two strips of aluminium foil. Will she succeed? Explain, how? 

Ans:  Aluminium is a metal that conducts electricity well. Yes, the aluminium foils will serve as connecting wires, attaching one strip to the bulb's negative terminal and the other to the bulb's positive terminal.

Long Answer Questions

20. Boojho has a cell and a single piece of connecting wire. Without cutting the wire in two, will he be able to make the bulb glow? Explain with the help of a circuit diagram. 

Ans:  With the suggested configuration, he will be able to light the bulb. He can connect one of the bulb's terminals straight to the electric cell's negative terminal. As a result, he won't require any additional cable for our electric circuit. The diagram depicts the needed setup:

21. Fig. 12.10 A and B show a bulb connected to a cell in two different ways. 

seo images

                                          Fig. 12.10

(i) What will be the direction of the current through the bulb in both cases? (Q to P or P to Q) 

Ans: Current always flows from a battery's positive terminal to its negative terminal throughout the circuit. In the example of current flow from Q to P, current will flow from the positive terminal Q to the negative terminal P. Whereas, in the case of P to Q; current will flow from the negative terminal P to the positive terminal Q.

(ii) Will the bulb glow in both cases?

Ans: Because the current is flowing in both circumstances, the bulb will light up.

(iii) Does the brightness of the glowing bulb depend on the direction of current through it? 

Ans: Whether the bulb glows brighter or duller depends on the circuit’s quantity of current and voltage. The direction of the current flow has no impact on it.

22. Think of six activities that use electric current. Also, name the devices used to perform the activity in tabular form. One example has been done for you: 

Activity you perform


Example- Get light













Activity you perform


Example- Get light

23. A torch is not functioning, though contact points in the torch are in working condition. What can be the possible reasons for this? Mention any three. 

Ans: The reason for the faulty functioning of the torch can be:

i. The cells may be disorganised.

ii. The filament of the bulb might be fractured, causing the bulb not to ignite.

iii. The cells may be depleted.

iv. The switch is defective.
