Hello all steemians now i will share to you about review topic that How to Make Natural Batteries from Potatoes. This topic not new ones but many other peoples tried it experiment. Believe it or not if in nature it actually has many sources of energy? There is an alternative electric energy that can be developed in the future, this is a physics experiment on electricity that can be tried at home.

# Tools and Materials 1. Potato (here we use potatoes, but you use lemon or other fruit if interested) 2. LED light (or small light bulb can also) 3. Cable 4. Crocodile clip 5. Copper plates 6. Zinc plates 7. For copper and zinc substitutes this can be used in battery contents which are usually black.

Procedure

1. Plug copper and zinc plates into potatoes with a few milli / centi (do not put them together). 2. Attach the cable to each plate and connect with the lamp. 3. See the lights that occur. 4. If the flame is not visible, try to reverse, but if it does not flame also then please add the potato so the electric current generated bigger (see picture). 5. For more than one Potato, connect: - 1st potato copper plate to lamp (+) - Zinc potato plate 1st to copper potato plate 2nd - 2nd zinc potato plate to the potato copper plate 3th - and so on, until the last zinc plate connects to the lamp (-).

# Concept Explanation The lamp can be illuminated due to the flow of electric current. As well as the flashlight battery, potatoes and plates that generate electricity even though very weak. The potato sap affects the metals chemically like the electrolyte solution in the battery. By akren aitu, an arrangement like this is dissolved by the galvani element, because the first to observe this process in an experiment was an Italian doctor named Galvani.
