Chapter 273: Start your old business!

"Master, Xiao Xi has brought your change of clothes!"
Li Zexuan returned to Zuifengxuan. About a quarter of an hour later, he didn't wait for Fu Bo to deliver materials, but waited for Xiao Xi to deliver clothes.
"Well, hard work, Xiao Xi, you can go back after putting these clothes in the back room!"
Li Zexuan said on several cases while recalling relevant knowledge of physics and chemistry in previous lives.
"Master, Madam is worried that you will suffer here alone, so she told Xiao Xi to stay here to take care of you too! Your three meals a day, Xiao Xi will go back and bring it for you!"
Xiao Xi turned around and said, holding the baggage she brought over.
"Huh~? My mother really said that?"
Li Zexuan raised his head and asked.
"Of course... Yes, Xiao Xi went to clean up the room for the young master!"
Xiao Xi replied with a flushed face, then hurriedly turned around, holding the package and went inside.
In fact, after Sambo sent back the news that Li Zexuan would be staying in the workshop for a few days, Mrs. Li really didn’t expect to send a maid to take care of her son’s diet and daily life. Xiao Xi said weakly behind. Mrs. Li sent her here.
When thinking about it, Mrs. Li's meaningful eyes and smile made Xiao Xi's ears red with shame.
.........
"My boss, this is the material that Fu Guan asked the little one to send over!"
Not long after Xiao Xi entered the back room, Song Xiaosi brought a package. After experiencing the lesson last time, Song Xiaosi's smile now carries a trace of caution, and he no longer laughs and laughs like Meng Lang as before.
"Ok."
Li Zexuan took the package, opened it and checked it carefully, and then nodded with satisfaction: "Very good! One is not bad, you can go back to the fourth, it's almost time for work!"
"Master, the younger one is not in a hurry. You can also live in the workshop at night, or you can stay here for the younger ones. If you have any instructions then, the younger ones can run errands for you, right?"
Song Xiaosi smiled diligently.
"No, there's nothing wrong with me, I'll do it alone, you should go back, Xiaosi!"
Li Zexuan smiled and replied.
At this moment, Xiao Xi cleaned up the room, and came out and said, "Master, your room is cleaned up!"
"Well, hard work!"
Li Zexuan nodded.
"Ah~! Master, then, that little one quit!"
When Song Xiaosi saw Xiao Xi, he immediately reacted, and at the same time he hated himself for talking too much. The young master of his own is a red-sleeved scent, so I don't need to come and help myself.
"Hey!"
When Li Zexuan saw Song Xiaosi running away, he knew that this kid had thought a lot, and planned to call him back, but after thinking about it, he felt it was fine. There was no explanation for this kind of thing.
"Xiao Xi, there is a wing room on the east side. Go and clean it up by yourself. Master, I'm going to start working!"
Li Zexuan mentioned the big bag of experimental materials, walked to the room, and smiled at Xiao Xi.
"Oh!"
Seeing that Li Zexuan doesn't need her help, Xiao Xi said "Oh", and Yiyan went to another room to clean up the room. After all, she would live here at night, so she couldn't sleep in the same room with Li Zexuan, right? Although she has thought about it, but...
.......................
"Hey, after having traveled for so long, I finally got my way!"
Li Zexuan put the package of materials on the "experimental table" he temporarily put together with four long tables. Looking at this simple "laboratory", he felt a little emotional for a while.
As an engineering student, and also an engineering student of his profession, I didn’t know how many circuit boards had been soldered in the laboratory before. I didn’t expect to travel to the Tang Dynasty and still have to do his job. The difference is that his current experimental conditions are even better. Shabby, of course, the experiments done are more basic and simpler, incomparable with modern integrated circuits.
"Starting, today this young master will let the battery come to this world more than a thousand years in advance, haha! Dear Mr. Volt, I'm sorry for stealing your Ming!"
Li Zexuan eagerly muttered to himself.
Yes, what Li Zexuan has to do is the simplest voltaic battery. what? Do you think the voltaic battery is weak, so why not build a motor?
Damn, big breasted brother, you don't have a backache when you stand and talk, and you want to run without learning how to walk. You think the motor is so easy to build! You traveled to the Tang Dynasty, come and make me a try? You can make it without a month or two? Li Zexuan now wants to generate electricity immediately, and then realize his next plan. How can one or two months be spent on making the motor?
Li Zexuan had watched the TV series "Mythology" in his previous life. In it, the Yi Xiaochuan played by Hu Ge traveled to the Qin Dynasty. Because the mobile phone ran out of power, he made a hand-cranked motor... This is of course the screenwriter's nonsense. Things can't get electricity at all.
Okay, magnets existed in ancient times. The wire used is the gold thread on the clothes of the future Mrs. Liu Bang, Lu Hou, but his gold thread does not have an insulating skin. It is no different from a gold lump when wound into a coil. The screenwriter doesn’t know. The real motor coil is enameled wire, not to mention rectification and voltage stabilization to charge the mobile phone... In addition, to charge the mobile phone, don't you need an interface cable...
Li Zexuan, who was born in science and engineering, had been struggling with this matter for a long time. He also thought at the time that if he really traveled to ancient times, when he needed to recharge his mobile phone, he should "adjust to the times" (the ancient materials were limited), and what kind of device would be good? Is it a simple hand crank motor, or some other weird stuff?
what? You said that there was no signal in ancient times, why do you charge your phone? You can use your mobile phone as a video camera. Is your mobile phone only for making calls? If there are some expansions in the phone, and use the past to contribute to the emperor, maybe you will have all the glory and wealth of your life...
After thinking hard and putting dogs and pigeons to find needles on the Internet, he really found it...
In 18oo, the famous scientist Volta (in fact, it is Volt, and the unit of voltage is Volt. I don’t know why those idiot translators in China call him Volta for a while, Volta for a while. When Li Zexuan was in middle school, his little mind was often Confused), understand that the world’s first battery is also the ancestor of modern batteries.
He found through experiments that a piece of paper impregnated with salt water between two different metals can generate electricity. He soaked in salt water with blotting paper, stacking a layer of silver flakes, a layer of blotting paper, and a layer of zinc flakes, and then connected the top metal sheet with the bottom metal sheet with wires~www.mtlnovel .com~ Now you can measure voltage and current. This device is now called a "voltaic stack".
The principle of the voltaic battery is that after two different metals and the electrolyte solution are in contact, the ions in the solution form a directional movement to generate an electric current.
Until now, the dry batteries we have used are modified voltaic batteries. In dry batteries, ammonium chloride paste is used instead of salt water, graphite rods are used instead of copper plates as the battery's positive electrode, and the outer shell still uses zinc skin as the battery's negative electrode.
Is it easier to make a battery compared to making a motor?
