What is a lemon battery?

Lemon battery is a classic scientific experiment used to demonstrate the foundations of the chemical battery system. To perform this experiment, a scientist needs one very juicy lemon, a galvanized or a zinc steel nail and a clean copper coin or part of the copper engagement. The scientist who produces the battery also needs an alligator buckle wire at each end and a sensitive voltmeter. Voltmeters can usually be found in the power supply section in the Hardware store, an electronic hobby shop or a center to improve your home. Small light emitting diodes (LEDs) and other electrical devices can also be used to test lemon battery, although it usually requires additional lemons.

How does it work

The

lemon battery relies on electrons and the chemical reaction that occurs when the metals are introduced into an acidic mixture. The lemon contains a significant amount of acidic juice that is in scientific terminology with an "electrolyte". Electrolyte acid helps to decompose metal structure, such as copper and zinc, causing the release of individual electrons. When a scientist creates a circuit, the connection of two metals to the conductor flows through the electrons as an electric charge that can be detected to a voltmeter or other device.

Battery Creation

First, the scientist would create a lemon battery carefully insert a copper coin or copper cabling into one end of the lemon and then insert a galvanized nail into the opposite end. It is important that the scientist to make sure that these two metals will follow each other. This would close the circuit and hold metals while affecting, can lead to a slight electrical shock.

Creating a charge

on the nail and coins have now become electrodes. Both copper and zinc allow electrons to flow, which means that they have been consoled by excellent wires of electricity. Copper coin or wire is considered to be a positive (+) electrode, while a nail coated with zinc is negative (-) electrodes.

free flowing electrons found in the electrolyte lemon juice naturally want to move from negative electrodes. How fast these electrons are measured as amperage. The voltmeter is lifted by displaying the voltage, indicating the "electrical pressure" operating in the circuit.

voltage measurement

One lemon battery does not create a significant amount of voltage, but a sensitive voltmeter should detect some electric output. The scientist should combine a positive wire clip, the end of the red case, the copper coin or the wire; and a negative clip, end with a black case, for a galvanized nail. Digital reading or an analog dial on the voltmeter should show a small voltage number, usually less than one tenth of the volt. This is not usually ENIGH to start digital clock or power the bulb, but it shows that the electric current was created by a chemical reaction in the lemon battery.

Increase of charge

While is a lemon battery with one funk cellIt provides little meaningful electric charges. Another voltage can be ensured by an increase in the number of cells or lemons in the battery. Many lemons can work together as the only battery through other wires connected from a positive electrode, copper part, one lemon to a negative end, zinc nail, the other.

about four lemons in the series in this way should provide enough energy to light up a small LED. The scientist should combine negative leadership from one end of the lemon to the LED wire closest to the flattened area of ​​the case. It can then attach a positive line, from the second end lemon to the second wire. In the middle of the LED, a matte but noticeable glow should light up; Additional lemons or cells can be added to the battery for greater charge and even brighter glow.
