Answer:
Potato battery or Vegetable battery
Step-by-step explanation:
Using a potato to light up a light bulb is an example of an experiment in which chemical energy is converted into electrical energy. This process is called a potato battery or a vegetable battery. It works by creating a simple electrical circuit between two electrodes (usually copper and zinc electrodes) inserted into the potato. The potato acts as an electrolyte, allowing charged ions to move between the two electrodes, generating an electric current that can be used to power a small device like a light bulb.
The potato battery is often used as an educational tool to demonstrate the basic principles of electricity and energy conversion.
