Introduction Explanation of how to use DV lemon to generate electricity. Quickly insert clean copper foils and zinc foils (can be peeled off from old dry batteries and then washed) separately into the lemons (don't touch them together) and a cup of water.

Explaining how DV Lemon technology generates electricity Urgent Urgent Urgent

Insert clean copper foils and zinc foils (can be peeled off from old, dry, washed batteries) separately onto the lemon (do not touch them together), and a fruit stack is created. The copper foil is the positive electrode of the battery and the zinc foil is the negative electrode. Connecting more in series can increase the voltage, and connecting in parallel can increase the current. [Course topic]: Making and operating electric lemons

[Principle]: Lemons contain a lot of citric acid, which can generate positive and negative electrons when in contact with leaves copper and zinc.

[Steps]: 1. Take a paper cup and draw your favorite pattern

2. Squeeze the lemon juice onto the sponge sheet.

3. Take a piece of copper and a piece of zinc and place them on both sides of the sponge dipped in lemon juice, then wrap them.

4.Pretie a piece of wire and attach one end to the piece of copper. Take another wire, attach it to the zinc sheet and place it into the glass tube.

5. Connect the copper pieces of the four glass tubes to the zinc pieces of the other and connect the four glass tubes in order.

6. Both ends of the two remaining wires are not fixed. Connect the wire connected to the copper foil to the positive electrode of the light tube, and the wire connected to the zinc foil to the negative electrode. of the luminescent tube.

7. You're done! The light tube can shine! !

Principle of fruit energy production

Lemon is one of the most medicinal fruits. It is rich in vitamin C, sugar, calcium, phosphorus, iron, vitamin B1, vitamin B2, etc. , very beneficial to the human body. You can use it to make tea, make jam... but you shouldn't think that you can also use it to produce electricity.ctricity, which can also light a small light bulb!

I was still skeptical when I saw this. How can a lemon produce electricity? So we usually eat lemons without being shocked? What is this phenomenon? All kinds of questions made me want to answer them, so I opened my winter vacation homework book and found a lemon, a copper nickel, a galvanized screw, two wires and a light emitting diode . I looked at the book and followed the steps in the book to soften the lemon, rub it on the table, then insert most of the screw into the lemon, then I took a pair of scissors and cut the other side of the lemon. . Make a one centimeter deep incision and insert the majority of the copper nickel into the incision. As the picture shows, the coin is the positive pole and the screw is the negative pole. Then connect the positive and negative terminals of the lemon battery and the two terminals ofthe light emitting diode with wires Seeing that I couldn't connect them for a long time, my father couldn't help but help me repair the wires.

But the result disappointed me. No matter how hard I tried, the little light bulb never came on. This experience left me with a big question mark about whether lemons can produce electricity. Is it written in this book that this is a lie? Can't lemons produce electricity? Dad, who was silent next to him, came over and said, "Can you use a voltmeter to check if there is electricity?" "What a great idea! I excitedly took the voltmeter and placed the measuring pens on the coins and the nails respectively. The meter showed 1.012 volts of electricity. "There really is electricity , so why doesn't it turn on? "I asked in puzzlement. Maybe the battery was too small! TryHave to add another lemon. So I brought another lemon. After connecting it, I measured it with a voltmeter and found that the voltage this time was 1.817 volts. I connected the small bulb again and found that it still wouldn't light up. This made me very frustrated. Why didn't the little light bulb still light up? I wanted to give up, but then I thought I had to get online. four lemons in series and tested it with a voltmeter. This time it was 3.54 volts. I turned the bulb off again and left it on!

Why do lemons produce electricity? I couldn't figure it out after searching on the internet. It turned out that lemons contain a lot of electricity, and citric acid is a good electrolyte. insert two different metal electrodes into a lemon, it will generate electricity like a battery.

The vie is everywhere, and with this science, our lives will be more exciting and. happier.

We cannot talk about electricity production... The principle of producing only short-term electricity is to use carbon rods/copper sheets (positive electrode) and zinc sheets (negative electrode). inserted into the banana and connected with wires.

The acid in the banana is the electrolyte, so there will be current from the negative electrode to the positive electrode (the zinc sheet releases electrons out of the circuit and flow into the carbon rod/copper foil)

The generated current can "generate electricity" 2011-04-11 22:36:10 Supplement: not just bananas

Apples Oranges, lemons, grapes, all sour fruits

Their acids can be used as electrolytes to "generate electricity" 2011-04-13 20:15: 35 Supplement: 002: You can fill in your comments next time Let's go revLet's talk about it in the opinion section: Generally speaking, more acidic fruits tend to contain more hydrogen ions. These extra hydrogen ions make the conductivity stronger, so the electricity will be greater.

Reference: Knowledge is power.

When you connect a light emitting diode to the metal piece of a lemon with one side open, the light emitting diode lights up and the lemon filled with zinc and copper pieces is an electrochemical battery. When two or more batteries are connected together, a battery is formed. All batteries have a negative electrode, which is the zinc plate in the experiment, and a positive electrode, which is the copper plate in the experiment. Zinc flakes release electrons more readily than copper flakes, and acidic lemon juice acts as an electrolyte or electrolyte. The electrolyte contains charged particles, appelated ions, which can penetrate the electrodes. Acidic substances are good electrolytes because they form ions in water. This chemical change acts like an electronic pump, pushing electrons from the wire to create an electric current. If you observe the condition of the zinc sheets after a while, you will find that some zinc sheets appear corroded and there are some small bubbles around the copper sheets. These bubbles are actually hydrogen gas broken down by the electrolyte. . Each battery puts out a tiny amount of voltage, but not enough to light the LED. When you connect three open lemons together, you will see the LEDs light up. In effect, the connected lemons form a series circuit, increasing the overall voltage and causing the LEDs to light up. Lemons work better as batteries than other fruits because they are more acidic. The lemon battery made above will emit approximately 0.7 volts. 2011-04-23 12:27:11 Supplement: The acid in the fruit is used as an electrolyte~~ As long as the fruit is slightly acidic

it can generate electricity with metal~

Reference: Yahoo

Generally it can only send 1.2-1.9V electricity

Hmm...but I want to know more about bananas

I only know that Apple offers You can generate electricity by using the canal gegen to generate electricity
