Which fruits and vegetables can produce electricity (Which fruits can be used to generate electricit

1. Almost all fruits and vegetables can generate electricity, but the degree of electricity generation is different.

2. Lemon, watermelon and dragon fruit have high energy production.

3. Strawberry, apple, pear, average energy production.

4. Potatoes, bananas and papayas have low electricity production.

5. The juice contained in fruits or vegetables contains a substance called “electrolyte”, which is a precursor for producing electricity.

6. Fruits and vegetables can produce electricity because they contain a lot of free water. Some of the minerals they contain are in an ionic state and can move freely, which will occur under the attraction of electrodes. different properties. Directional movement produces electric current.

Did you know that the fruit will be a little flaky? Today I had this experiencee interesting with my parents.

The materials to prepare for this experiment are: two oranges, two copper wires, two galvanized iron nails and a light-emitting diode.

First of all, I tried. I took out two oranges and plugged them into the copper wires. However, the oranges seemed to be like an ugly doll competing with me. I inserted the "skin" of the oranges, it just wouldn't break. I put a lot of effort into “pushing” it in. Then I inserted the galvanized iron nail, wrapped the wire around the iron nail and connected the wire head. to the light-emitting diode. However, the light-emitting diode seemed to be a joke. It seemed like its dim light was flickering and then there was no movement, but the diode seemed asleep and. there was no movement. The first test failed. I was very upset and started to check which part was causing the problem: could it be that thes materials were not good? But the fruits are all bought from the fruit store, and the copper wire and gold-plated iron nails are all bought from the hardware store. Is this the wrong place? I swapped the two positions and connected the two oranges separately, but during the connecting process, my father told me: "Knead the oranges continuously until they become soft, because the juice of the oranges needs to circulate to produce electricity. orange according to dad's words, then I connected the two wires to the light emitting diode. The diode emits a weak light, I succeeded!

But I was very confused. Dad saw my puzzled look and said: "The principle of orange energy production is: the electrochemical activity of two metal sheets is different, such as copper wire and galvanized iron nails, which is more active . The metal (copper) on the other side reacts chemically with the acidic substances in the fruit to generateer a positive charge, and the other side (zinc) generates a negative charge. It is this difference in chemical energy that is converted. in electrical energy.

Over time, the tension in the orange will decrease. The contact area between the copper wire and the galvanized iron nail will turn black. As long as the metal connection is changed, it turns black. can continue to produce electricity.

In addition, Dad also said: “In addition to oranges, pineapples, lemons and other sour fruits can also generate electricity. »
