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.
Solution:
The complete circuit diagram so that the bulb glows is given below:
NCERT Exemplar Class 6 Science Chapter 12 Electricity and Circuits Img 6

Question 11:
Will the bulb glow in the circuit shown in figure? Explain.
NCERT Exemplar Class 6 Science Chapter 12 Electricity and Circuits Img 7
Solution:
As in the given circuit diagram, it seems that the switch is open, i.e. there is an air gap between the connecting wires, so the circuit is not complete and therefore, the bulb will not glow.

Question 12:
An electric bulb is connected to a cell through a switch as shown in figure. When the switch is brought in ON position, the bulb does not glow. What could be the possible reasons for it? Mention any two of them.
NCERT Exemplar Class 6 Science Chapter 12 Electricity and Circuits Img 8
Solution:
The possible reasons so that even at switch ON position the bulb is not glowing are:
(i) The cell may be discharged.
(ii) The bulb may be fused.
(iii) The wire may be broken from inside.
(iv) The connections may be loose.

Question 13:
A torch requires 3 cells. Show the arrangement of the cells with a diagram inside the torch so that the bulb glows.
Solution:
The arrangement of bulb should be such that the positive terminal of a battery touches the base of the bulb. When switched ON, the bulb will glow.

Question 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 case of rechargeable batteries (such as the type used in mobile phones, cameras and inverters), they are used again and again. How?
Solution:
A rechargeable battery has such chemicals which on after usage can be restored, by passing a suitable current in the opposite direction to the rechargeable battery, so that it can be used again and again.

Question 15:
Paheli connected two bulbs to a cell as shown in figure.
NCERT Exemplar Class 6 Science Chapter 12 Electricity and Circuits Img 10
She found that filament of bulb B is broken. Will the bulb A glow in this circuit? Give reason.
Solution:
No, the bulb A will not glow in the circuit because the filament of the bulb 8 is broken and the current will not pass through it, i.e. the circuit is broken or incomplete. Therefore, the current will not flow in the whole circuit.

Question 16:
Why do bulbs have two terminals?
Solution:
Bulb has two terminals to connect the filament with the terminals of a cell or a battery so that the current can pass through the filament.

Question 17:
Which of the following arrangement A, B, C and D given in figure should not be set up? Explain why.
NCERT Exemplar Class 6 Science Chapter 12 Electricity and Circuits Img 11
Solution:
Arrangement A should not be set up because in this arrangement cell will be used up very rapidly as no appliance is connected between the two terminals of the cell.

Question 18:
A fused bulb does not glow. Why?
Solution:
A fused bulb does not glow because in a fused bulb, the filament is broken and the circuit is incomplete. Therefore, the current does not flow through it.

Question 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.
Solution:
Yes, she will succeed. Aluminium foils can act as connecting wires because aluminium is
a conductor of electricity, it will complete the circuit and therefore, the bulb will glow.

Long Answer Type Questions

Question 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.
Solution:
Yes, this can be done by arranging the circuit as given below:
NCERT Exemplar Class 6 Science Chapter 12 Electricity and Circuits Img 12
In this arrangement, one terminal of the bulb should be connected directly to the positive (say) terminal of the cell and the other terminal of the bulb should be connected to the negative terminal of the cell using the given piece of connecting wire.

Question 21:
Figures A and B show a bulb connected to a cell in two different ways.
NCERT Exemplar Class 6 Science Chapter 12 Electricity and Circuits Img 13
(a) What will be the direction of the current through the bulb in both the cases (Q to P or P to Q)?
(b) Will the bulb glow in both the cases?
(c) Does the brightness of the glowing bulb depend on the direction of current through it?
Solution:
(a) The direction of current will be from 0 to P in A and direction of current will be from PtoQ in B. This is because the direction of current is always from positive terminal to negative terminal of the cell or battery. This is the conventional direction of flow of current in the circuit.
(b) Yes, the bulb will glow in both the cases because for the bulb to glow, we just need to complete the circuit.
(c) No, the brightness of the bulb never depends upon the direction of current passing through it.
