What fruits & vegetables conduct electricity?

Updated February 21, 2017

Fruits and vegetables contain important vitamins and minerals our bodies need to maintain itself properly. These same fruits and vegetables also contain a large amount of water. The water in all fruits and vegetables makes them good conductors of electricity. Other ingredients such as citric acid and ascorbic acid increase the conductivity, creating more voltage.

Vegetable Electricity Conductors

Potatoes, onions and tomatoes are all good vegetable conductors. Tomatoes are most likely the best vegetable conductor since they have the highest acidity level.

Fruit Electricity Conductors

Some good fruit electricity conductors are apples, grapefruit, oranges, lemons and limes. The citrus fruits will be excellent conductors due, again, to the high acidity level.

Making a Circuit

When a fruit or vegetable is connected with electrodes in a circuit, the fruit or vegetable serves as the battery to complete the circuit and light a small light bulb.

Current and Voltage

If several pieces of fruit or vegetables are connected in a parallel circuit, it gives off a

higher current. If the fruit or vegetables are connected in a series arrangement, the voltage is increased.
