how can potatoes produce electricity
Hello, Tasia. I'll try to explain how a potato can be used to generate electricity. The potato itself has a mixture of starches and salts and some water. A salt, like table salt, in water releases ions.Ions are atoms that have an electrical charge.able salt releases two electrically charged ions-a sodium ion with a positive charge, and a chlorine ion with a negative charge. To make a battery with a potato, you need to put two different metals into the potato...the metals can be zinc and tin, or copper and steel, or other choices.
