प्रश्न
Rahul wants to make an electric circuit. He has a bulb, two wires, a safety pin, and a piece of copper. He does not have any electric cell or battery. Suddenly he gets some idea. He uses lemon instead of a battery and makes a circuit. Will the bulb glow?

उत्तर
Yes, the bulb will glow:
- Take a lemon. Squeeze it without breaking its skin. The squeezing action releases the juice inside the lemon needed as the battery works.
- Use a nail to make one hole in one end of the lemon and push a copper wire into that hole.
- Then, push the nail into the other end.
- Connect a bulb with one of the terminals with the copper wire and the other terminals with the nail, as shown in the figure.
- Now the lemon generates a small amount of electricity and the bulb glows.
