Salt Water Battery
Introduction:
This project is one of the most famous electricity projects that can be performed successfully by most students in the age of 10 to 16. It helps students to learn about producing electrical energy using chemical energy. Since the same method is used to get energy from many fruits and chemicals, this project has many names. Following are some of the other names or titles for this project:
|Fruit power or fruit battery | |
|Convert Chemical energy to electrical energy | |
|Potato battery or Lemon battery | |
Procedure:
Making electricity from chemicals is based on the same scientific principles on which all modern batteries work. You insert copper and zinc electrodes in an acidic liquid and produce some electricity from the chemical reaction between your electrodes and electrolyte.
|The electricity produced in this way can be displayed with a multi-meter | |
|that can show millivolts. It may also be able to produce enough electricity | |
|to get light. If you want to run or light up a device you must consider the| |
|voltage and current requirements of that device. | |
|Picture in the right shows 3 potato batteries connected in series so | |
|together they will produce enough voltage to light up a super bright LED | |
|type light source. |
