In a chemical battery, the direct conversion of chemical energy into electrical energy is the result of spontaneous chemical reactions such as oxidation and reduction inside the battery. This reaction takes place on two electrodes. The negative active material consists of a reducing agent with a relatively negative and stable potential in the electrolyte, such as zinc, cadmium, lead and other active metals and hydrogen or hydrocarbons.
The positive active material is composed of positive potential and stable oxidants in the electrolyte, such as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or air, halogens and their salts, including oxyacids. and their salts, etc. Electrolytes are materials with good ionic conductivity, such as aqueous solutions of acids, alkalis and salts, non-aqueous organic or inorganic solutions, saltss molten or solid electrolytes.
When the external circuit is disconnected, although there is a potential difference (open circuit voltage) between the two poles, there is no current and chemical energy stored in the battery is not converted into electrical energy.
When the external circuit is closed, current flows through the external circuit due to the potential difference between the two electrodes. At the same time, inside the battery, since there are no free electrons in the electrolyte, the charge transfer must be accompanied by oxidation or reduction reactions at the interface between materials active bipolar and electrolyte, as well as material migration of reactants and reaction products.
Detailed informationA battery is a device that converts chemical energy into electrical energy. It has positive and negative poles. With advancements in technology, batteries are becoming increasinglygenerally referring to small devices that can produce electricity. Like solar cells.
The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Using the battery as a power source, you can achieve power with stable voltage, stable current, stable power supply for a long time and little influence from the outside world. The battery has a simple structure, is easy to carry. Simple and easy charging and discharging operations, and is not affected by the impact of external climate and temperature, the performance is stable and reliable.

Slow video showing how to operate the water meter
This looks like it was taught in college in physics or chemistry. The moleculesof water are polar and will undergo directional movement under the influence of electric fields. Microwave ovens use high-frequency alternating electric fields to cause water molecules to move rapidly to achieve heating. As for the poster's question about using an electrostatic field to levitate water molecules, it seems theoretically possible, but it's only theoretical. Since the polarity of water molecules is so small, how large must an electric field be to balance the gravity of the water molecules. A strong enough electric field to this degree can probably ionize water?
Question 1: How can a mechanical water meter slow down its speed? Is there a way to steal water? Use drops of wax on the watch
Question 2: How to make the water meter work slowly or not This is related to the theory of relativity. YOUcan find a university to study. for a certain time. Chicken
Leave the tap running and the water meter will stop working. One night it will be a bucket [.Offline]
This is the correct answer. I've always done that. The watch is so slow! Big tree.
lz uses hot water~ it will be cold when it is full~
20 yuan for 1 word! ! [Disconnected]
Use cold water and heat it yourself. I usually don't bother answering such a simple question.
I love using the shower! ! ! Big tree.
Liz pays great attention to saving water ~ I usually use a bucket to wash my face and feet, then flush the toilet! !
Use the water used to wash clothes to clean the floor! ! ! '
But the bath water is a bit expensive, 20 yuan! ! !
Please give me some advice! !

I havetense to say that you could use this kind of strong magnet_Kay
Find someone who knows physics and electricity to help you repair your water meter
Your mother [beep--]
Our school is like that too! ! ! Exorbitantly expensive! ! ! He often collects randomly and shamelessly! ! ! Dumplings
It's an old water meter. This type of water meter has been removed. The strong magnet is useless

Pour the water more slowly. It's best if Didi is a natural partner.
Question 3: How can the water meter slow down? This will not work so that the water meter does not spin. discovered by the water company. You can slow down the speed slowly! Method: remove the watch yourself, open the watch "use special pipe tool", remove the gear inside, rub the gear with rough surface of the outit, increase the friction when rotating, reduce the speed of the water meter, and the meter will rotate slowly, if at all. Effect
Question 4: How to make the tap water meter run more slowly? It is not possible to prevent the water meter from running slower. rotation. This will be discovered by the water company people, so it can be slowed down!
Method: 1. Remove the watch by yourself, open the watch "using a special pipe tool", take it out. The gear inside and rub the gear with a rough surface of the tool to increase friction and reduce friction when it rotates. The speed of the water meter can achieve the effect that the meter turns slowly or even does not turn! > Method: Second, the simplest method is to adjust the water inlet and outlet of the water meter. You will find that when using water, the index will continue to dimminuate.
Disadvantages: Easy to catch.
Third method, remove the water meter, then place a small stone in the water inlet. It should not be too small, because it will be evacuated, and it should not be too big, because it. This will affect the flow, so put it back so the water meter doesn't spin.
Question 5: How to slowly rotate the water meter to save water.
Increase the air pressure in the water meter ( good sealing) and increase the friction of the pointer operation can block the finger to a certain extentThe movement of the needle means the water meter works slowly
Remove the gear inside and rub the gear with a rough surface of the tool to increase friction when rotating and reduce the speed of the water meter
This is not very ethical. It is recommended not to do this.
Question 6: The water meter leaks relatively quickly. make it run slower (steal water)? See the explanation of the problem in the poster with images and texts, and it is clear and coherent. IQ and knowledge are in no way lower than ordinary people :)
It really is. It's not worth using your wisdom on small water stealing skills, haha. Stop begging. Stand up and hold your head high.
Good luck on the way!
Question 7: How to adjust the water meter Go slower 1. Magnetic method: select a few super strong magnetic field magnets (the hard disk one is strong enough) to attach to the water meter and rely on the magnetic force to reduce the speed of the pointer.
2. How to dismantle the meter: find a friend who worked in a water factory to help you remove the meter, loosen the fourstopwatch reading screw inside, then reinstall the meter, so that the single digit on your water meter is It turns very slowly. This method is not recommended because it violates the domestic water use agreement and people who do not know how to disassemble the meter can easily damage it.
Question 8: Can magnets slow down the operation of the water meter? First of all, if it slows down the water meter it must be illegal Haha, you just need to know the method. , but don't do it.
p>
1. Run the water from the tap so that the water meter does not reach the initial flow rate
2 . Open the water meter and open the three adjusting nut holes under the gear. This is often done to check the speed of the water meter.
3. If the water meter has been used for a long time, you can open the water meter, clean the scale on the roue and the water meter can also be slowed down.
4. The most immoral way is to open the water meter and shorten all the rotating wheels
5. If it is a water meter For mechanical dry water, you can just get a big magnet and put it on it.
The above method is only for learning reference, do not perform it...
Question 9: How to slow down the operation of the water meter? is linked to the theory of relativity. You can find a university and study cauliflower chicken for a while

Question 10: Is there a way to slow down the water meter? There are three ways,
1.2; of the electric meter can go slowly
2. There is a small hook on connection 1.2 of the meter. Do not loosen it completely, otherwise it will not rotate
3. Connect. the neutral wire to the earth wire, < /p>
