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.
