Question

how to test whether a fruit or vegetable can conduct electricity​

Answer 1

When a fruit or vegetable is connected with electrodes in a circuit, the fruit or vegetable serves as the battery to complete the circuit. Some of them can even power small light bulbs for a time. Some researchers have shown that boiling a potato for around eight minutes can increase its capacity as a battery 10 times ...Citrus fruits work as excellent conductors , and Potatoes, onions, and tomatoes conduct electricity quite well. Tomatoes (not vegetables, strictly-speaking ) are good conductors in the vegetable category, as they have the highest acidity level.
