When a copper wire from a tester is inserted into a potato, a simple electrical circuit is formed. The potato acts as an electrolyte and allows the flow of electricity between the copper wire (which acts as the anode) and the surrounding environment or another electrode (which acts as the cathode). This setup creates a small electric potential.
The moisture and ions present in the potato facilitate the movement of electrons between the copper wire and the potato, allowing for a small current to flow through the circuit. This phenomenon is often used in simple science experiments or educational demonstrations to show how certain fruits and vegetables can conduct electricity due to their electrolyte content.
It's important to note that the voltage produced in such a setup is very low, and the purpose is usually educational rather than practical. The potato battery experiment is a popular way to demonstrate basic principles of electrochemistry and electrical circuits in a hands-on and accessible manner.
The potato turns greenish blue when connected to the positive terminal, the electrons from the negative terminal of the battery move inside the potato as the electrolysis occurs at the copper wire inside potato. This electrolysis conducted by the presence of starch in potato which produces more electrons.
