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. Electrical power increases as you connect more fruits.

According to the website MadSci.org, one raw potato has 407 milligrams of potassium, which acts as a conduit for electrical power. Potatoes may also have a higher number of ions that can produce electricity. Other vegetables that conduct electricity due to their potassium and ionic content are tomatoes, carrots, sweet potatoes and cucumbers.

Pickled Foods

Foods soaked in brine or otherwise pickled, such as pickles, conduct electricity due to their salt content. Salt is high in ions and conducts electricity. Foods high in salt content will produce electricity.
