WebThis experiment works by using a nail and a wire as terminals, and the juice of the apple acts as an electrolyte through which ions can flow. Rub the end of a zinc plated or galvanized nail gently with sandpaper. Strip the insulation off an 18-gauge copper wire. The wire should be about 4 inches long. WebElectronically measure how light is reflected from different color surfaces, and build a circuit that can differentiate between red and green produce. Introduction Many fruits and vegetables change color as they ripen. For example, tomatoes, strawberries, and red bell peppers all change from green to red.

The acidity of citrus fruit juice acts as an electrolyte that conducts electricity. Citrus fruits such as oranges, grapefruits, limes and lemons have high acidity levels. One lemon can produce 7/10 of one volt of electricity.

WebNov 6, 2024 · How does a fruit produce electricity? When you inserted the galvanized or zinc nail into the fruit, the negatively charged ions or the electrons started to move from the fruit to the zinc nail thus leaving the protons in the fruit. This transfer of electrons generates electricity as soon as you attach the wires to the nail, and the bulb lights up!
