Lemon battery experiments include the use of juicy lemon, copper coins and zinc nails to form a lemon battery.When four of these lemon batteries are combined together, they generate enough voltage to light up the LED (LEDs ).A classic scientific experiment used to demonstrate the fundamentals of a chemical battery system is a lemon battery.Lemon batteries can't run the motor, but they have the ability to produce dim light in the LED.The battery consists of two different metals: Copper and zinc soaked in acidic solutions.Copper metal is used as a positive electrode, and zinc metal is used as a negative electrode.All the batteries have a "and "-\" terminal.The acidic solution in the battery is called electrolyte.In the case of lemon batteries, acidic lemon juice is an electrolyte that helps to break down the atomic structure of zinc and copper metals.This leads to the release of a single electron.The flow of a single electron is called electricity.These electrons will flow from the negative pole of the battery to the positive pole.The measurement of the force of the moving electron is called voltage.This is the concept behind the lemon battery experiment.However, it is not easy to make a successful lemon battery.Take the first lemon and make a crack at one end.Make sure the lemon is juicy because the citric acid in the lemon acts as an electrolyte.Your battery will not work without enough lemon juice.Insert copper coins into the seam.Make sure your copper coins are clean.At the other end, make a similar slit and insert a galvanized zinc nail.Make sure DingTalk and coins don't touch each other.Coins and nails form positive and negative electrodes respectively, thus forming a single cell of the battery.Two electrodes that charge the opposite will now allow electrons to pass through them.The free electrons in lemon juice will be moved from the negative electrode (nail) to the positive electrode (coin ).Two electrodes are connected using the crocodile clip.The electricity will flow from the nail to the coin through the lemon juice electrolyte.The rate of electronic flow is called voltage.The faster the electron flows, the higher the voltage.The voltmeter will measure the electronic flow rate.If the voltmeter is connected to the electrode, the voltage is 0.906 Volts will be detected.However, this is not enough to light the bulb.In order to reach enough voltage to light the bulbs, one has to make more lemon batteries and connect them through the crocodile clip wires.Take the other three lemons and follow the same procedure from step 1 to step 4.Your four lemon batteries are ready and the total voltage is 3 if combined.50 volts, enough to light a small lampLEDs or LED lights.Connect the four lemon batteries to each other with the crocodile clip, so that the positive pole of one battery is connected to the negative pole of the other battery.For clarity, look at the image above.Connect the negative pole of the first lemon to the LED and the positive pole of the fourth lemon to the LED.Your circuit is done.The flow of electrons will occur from lemon 1 to 4 through 2 and 3 and then light up the LED.The Led works even at very low voltage (below 2 v) and low current.These LEDs will be damaged if connected to batteries above 2 volts.Therefore, they need resistance to control the battery with a rated voltage of more than 2 v.However, since the lemon battery produces low current, it is safe to connect the LED to it.However, copper coins can cause problems in this lemon battery experiment.The coin should be pure copper.People can replace coins with copper wire on the 14 th.Also, the coins should be clean.Have fun!
