ABSTRACT The Batteries form a significant part of many electronic devices. Typical electrochemical batteries or cells convert chemical energy into electrical energy. Batteries based on the charging ability are classified into primary and secondary cells. Secondary cells are widely used because of their rechargeable nature. Presently‚ battery takes up a huge amount of space and contributes to a large part of the device’s weight. There is strong recent interest in ultrathin‚ flexible‚ safe energy storage

Group 2 Science Investigatory Project I Title: Potato Battery II Objective: We only need a potato‚ a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails

POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ the

succeed from rags to riches and we already proved that to the world. From any kind of liquids that contains electrolytes‚ we can produce electric current out from it. Following an experiment from the Mesopotamians and today’s modern‚ “fruit battery”‚ we have constructed a simple machine that can be used at any time of need. Background Of The Study A thorough research for an exemplary Functional Investigatory Project that could be used as an inspiration came from the media such as

ABSTRACT 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
