Very Short Answer Type Questions
- In which of the following circuits A, B and C given in Fig. 12.4, the cell will be used up very rapidly?
- Fig. 12.5 shows a bulb with its different parts marked as 1, 2, 3, 4 and 5. Which of them label the terminals of the bulb?
Short Answer Type Questions
- You are provided with a bulb, a cell, a switch and some connecting wires. Draw a diagram to show the connections between them to make the bulb glow.
- Will the bulb glow in the circuit shown in Fig. 12.6? Explain.
- 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.
- A torch requires 3 cells. Show the arrangement of the cells, with a diagram, inside the torch so that the bulb glows.
- 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 case of rechargeable batteries (such as the type used in mobile phones, camera and inverters), they are used again and again. How?
- Paheli connected two bulbs to a cell as shown in Fig. 12.8.
She found that filament of bulb B is broken. Will the bulb A glow in this circuit? Give reason.
- Why do bulbs have two terminals?
- Which of the following arrangement A, B, C and D given in Fig. 12.9 should not be set up? Explain, why.
- A fused bulb does not glow. Why?
- 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?
Long Answer Type Questions
- 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.
- Fig. 12.10 A and B, show a bulb connected to a cell in two different ways.
- (i) What will be the direction of the current through the bulb in both the cases. (Q to P or P to Q)
- (ii) Will the bulb glow in both the cases?
- (iii) Does the brightness of the glowing bulb depend on the direction of current through it?
- Think of six activities which use electric current. Also name the devices used to perform the activity.
- 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.
