Think of six activities which use electric current. Also name the devices used to perform the activity.

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

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?

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.
