A Fruit battery is a device used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallic objects, for example a galvanized nail and a copper coin, into an ion bridge (for example a lemon, a potato or paper soaked in salt water or acid). The copper coin serves as the positive electrode or cathode and the galvanized nail as the electron-producing negative electrode or anode. These two objects work as electrodes, causing anelectrochemical reaction which generates a small potential difference.

- 1 medium size lemon or lime
- About 4 in. wire with insulation
removed, #12 or #18 works just fine
- 1 steel nail, #6 or 8 is ok
- 1 zinc plated nail, #6 or 8 is ok
- Small piece of sandpaper
- Knife or wire pliers (not shown) to
remove insulation
General Procedures
1.Set the fruit on a table and gently roll in around to soften it up. Youwant the juice to be flowing inside the fruit without breaking its skin.Alternatively, you can squeeze the fruit with your hands.2. Insert the zinc and copper nails into the fruit so that they are about2" or 5 cm apart. You don't want them to be touching each other. Avoidpuncturing through the end of the fruit.3. Remove enough insulation from the leads of the light (about 1") sothat you can wrap one lead around the zinc nail and one lead around the copper nail. If you like, you can use electrical tape or alligator clips tokeep the wire from falling off the nails.4. When you connect the second nail, the light will turn on.

The results were that the Fruit battery manages or rather produce electricity rating from 3v and above which proves it working. Analysis of Data:
When using the fruit battery to produce electricity the fruit differs depending on the fruit you are...
