Question

Why fruits and vegetables show electric conductivity?

Answer 1

Answer:

The combination of using two different metals and the conductivity of the juice of the fruit or vegetable allows for current to flow. Each fruit and vegetable will have different conductivity levels which makes some fruits and vegetables better able to conduct electricity than others.

Answer 2

Fruits and vegetables contain important vitamins and minerals human bodies need to survive and maintain themselves properly. However, interestingly, these same fruits and vegetables also contain a large amount of water and, thus, can in some cases conduct electricity well. Other ingredients such as citric acid and ascorbic acid increase the conductivity, and in some cases, the acidic content is high enough to create voltage that can power small electronics.
