Batteries store chemical energy and transform this energy into electricity. This is how batteries make gadgets and electronic devices work, like mobile phones, MP3 players, flashlights, and a whole lot more.
There are two main types of batteries based on the type of electrolyte it uses. There is what we call the wet cell, which makes use of liquid electrolytes in the form of a solution, and there is also what we call dry cell, which makes use of electrolytes in the form of paste. There are many more types of batteries available on the market now, like carbon-zinc cell, alkaline cell, nickel-cadmium cell, Edison cell and mercury cell.
In this simple experiment, we will be creating our own battery with the use of citrus fruits, with a power that is strong enough to make a small bulb light up. Later on, we will discuss how citrus fruits work as batteries.
