Food for Thought
1. Why Red LED bulb is preferred over LED bulb of other colors like yellow, green?
2. How long the light will glow?
3. Stick a second zinc electrode into one of the lemons, but don't connect it to anything. Any effect on the LED?
4. Try using fewer lemons to lit LED?
5. Who invented battery?
6. Which combination of metal will result in highest voltage for this lemon battery?
7. Lemon contains which acid?
8. Will the thickness of zinc and copper wire be same if this experiment is conducted for longer duration?
9. What will happen if we use short wires of zinc and copper?
10. What will happen if we use thick wires of zinc and copper?
11. What will happen if coiled wire is used instead of straight wire?
12. Can you calculate surface area of zinc and copper wire?
