Answer:

Activity: Fruits like lemon, potato, and tomato are tried as electric cells by inserting two different metal strips (such as copper and zinc, or copper and iron) into them. Several fruits or vegetables may be connected in series to increase the power, and an LED or small bulb is connected to check if electricity is produced.

Observations:

1. When copper and zinc metals are used in a lemon, the LED glows dimly.
2. More lemons connected together make the LED glow brighter.
3. With other fruits and vegetables such as potatoes and tomatoes, electricity is still produced, but lemons usually work the best because of their sour and acidic juice.
4. If plain water is tried instead of fruit, almost no electricity is produced.

Brief Report: Fruits like lemon or tomato, when combined with different metals, can act as simple electric cells and produce a small amount of electricity. The acidic juice in fruits helps in carrying the current. The choice of metals is important-combinations like zinc and copper are the best for making a fruit cell. This type of cell can glow a small bulb or LED if several are connected together, but they do not provide as much electricity as common batteries.
