"Master, Xiao Xi has brought all your changes of clothes!"
Li Zexuan returned to Zuifengxuan. About a quarter of an hour later, instead of waiting for Uncle Fu to deliver materials, he did wait for Xiao Xi to deliver clothes.
"Well, thank you for your hard work. Xiao Xi, you can just put these clothes in the back room and go back!"
Li Zexuan was leaning on several cases, recalling the relevant knowledge of physics and chemistry in his previous life as he spoke.
"Master, Madam is worried that you will suffer here alone, so she asked Xiao Xi to stay here to take care of you in the past few days! Xiao Xi will go back and get you three meals a day!"
Xiao Xi hugged the bundle she brought over and turned around and said.
"Huh~? Did my mother really say that?"
Li Zexuan raised his head and asked.
"Of course... yes, Xiao Xi went to clean up the young master's room!"
Xiao Xi responded with a blush on her face, then hurriedly turned around and went to the inner room with the package in her arms.
In fact, after Sanbao sent back the news that Li Zexuan would stay in the workshop for a few days, Mrs. Li really didn't expect to send a maid over to take care of her son's daily life. It was Xiao Xi who weakly mentioned it later. Mrs. Li then sent her over.
When she thought of Mrs. Li's meaningful eyes and smile, Xiao Xi's ears turned red with embarrassment.
... ... ... ... ... ... ... ... .
"Boss, this is the material that Manager Fu asked me to send over!"
Not long after Xiao Xi entered the inner room, Song Xiaosi arrived with a package. After experiencing the last lesson, Song Xiaosi's smile now has a hint of caution, and he no longer laughs at Meng Lang as before.
"Um."
Li Zexuan took the package, opened it and checked it carefully, then nodded with satisfaction and said: "Very good! Not bad. Xiaosi, you can go back. It's almost time to get off work!"
"Master, don't worry, I can stay in the workshop at night, or I can stay here. If you have any instructions, I can run errands for you, right?"
Song Xiaosi smiled enthusiastically.
"No, I don't have anything to do here. I can just do the work alone. Xiao Si, you should go back!"
Li Zexuan smiled and replied.
At this moment, Xiao Xi tidied up the room and came out and said, "Master, your room is tidied up!"
"Well, thank you for your hard work!"
Li Zexuan nodded.
"Ah~! Young Master, then, then, the little one, please leave!"
When Song Xiaosi saw Xiao Xi, he immediately reacted. At the same time, he secretly hated himself for talking too much. His young master was just adding beauty to his sleeves, so there was no need for him to come and help.
"Why!"
When Li Zexuan saw Song Xiaosi running away, he knew that this kid was overthinking it and planned to call him back, but after thinking about it, he decided to forget it. There was no explanation for this kind of thing.
"Xiao Xi, there is a wing on the east side. You can clean it up yourself. Master, I'm going to start working!"
Li Zexuan picked up the large bag of experimental materials, walked to the room, and smiled at Xiao Xi.
"oh!"
When Xiao Xi saw that Li Zexuan didn't need her help now, she said "oh" and Yiyan went to another room to clean up the room. After all, she had to live here at night, so she couldn't sleep in the same room with Li Zexuan, right? Although she had thought about it,...
... ... ... ... ... ... ... ... ... ..
"Hey, it's been so long since I traveled through time, and I'm finally back to my old profession!"
Li Zexuan placed the package of materials on the "experimental bench" he had temporarily put together with four long tables. Looking at this simple "laboratory", he felt a little emotional for a moment.
As an engineering student, and an engineering student in his major, he had soldered countless circuit boards in the laboratory before. He didn't expect that he would be in the Tang Dynasty and still work in his old profession. The difference is that his current experimental conditions are more It's shabby, of course, and the experiments done are more basic and simple, incomparable to modern integrated circuits.
"Work has started. Today, I made the battery come to this world more than a thousand years ahead of schedule. Haha! Dear Mr. Volt, I'm sorry for stealing your invention!"
Li Zexuan was gearing up and murmured to himself eagerly.
That's right, what Li Zexuan wants to do is the simplest voltaic battery. What? Do you think the voltaic battery is weak and exploded, so why not build a generator
Damn it, big-breasted brother, your back hurts when you stand and talk, and you want to run before you learn to walk. Do you think it’s so easy to make a generator? You traveled to the Tang Dynasty and came over to try to build one for me? Can you make it without a month or two? Li Zexuan now wants to generate electricity immediately and then implement his next plan. How can he spend a month or two to build a generator
Li Zexuan watched the TV series "Myth" in his previous life. In it, Yi Xiaochuan, played by Hu Ge, traveled to the Qin Dynasty. Because his mobile phone ran out of battery, he made a hand-operated generator... This is of course the screenwriter's nonsense. In fact, he The thing doesn't generate electricity at all.
Well, magnets existed in ancient times, and the wires used were gold wires from the clothes of the future Liu Bang wife, Empress Lu. However, those gold wires did not have an insulating outer covering. Wrapping them into a coil was no different from a lump of gold. The screenwriter didn't know The real generator coil is made of enameled wire, not to mention that charging a mobile phone requires rectification and voltage stabilization... In addition, if you want to charge a mobile phone, don't you need an interface cable...
Li Zexuan, who has a background in science and engineering, has been struggling with this matter for a long time. At that time, he also thought that if he really traveled to ancient times, when he needed to charge his mobile phone, he should "adapt to the times" (ancient materials are limited). What kind of device would be good to invent? Is it a simple hand-cranked generator, or some other weird thing
What? You said there was no signal in ancient times, so why did you charge your mobile phone? You can use your mobile phone as a camera, but your mobile phone can only be used for making calls? If you have some *** information packs on your phone, take them and contribute them to the emperor, maybe you will have a lifetime of glory and wealth...
After thinking hard and looking for the needle in the haystack on the Internet, he actually found it...
In 1800, the famous scientist Volta (actually it is volt, the unit of voltage is volt). I don’t know why those idiot translators in China call him Volta at one time and volt at another. When Li Zexuan was in middle school, his little mind was often Puzzle), invented the world's first battery and was also the ancestor of modern batteries.
Through experiments, he discovered that electricity could be generated by sandwiching a piece of paper soaked in salt water between two different metals. He soaked the blotting paper with salt water, stacked a layer of silver sheets, a layer of blotting paper, and a layer of zinc sheets, and then used wires to connect the top layer of metal sheets to the bottom layer of metal sheets. He found that he could measure Output voltage and current. This device is now called a "voltaic pile."
The principle of a voltaic battery is that after two different metals come into contact with an electrolyte solution, the ions in the solution move in a directional manner to generate an electric current.
Until now, the dry batteries we use 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 positive electrode of the battery, and zinc sheets are still used as the negative electrode of the battery.
Is it easier to make a battery than a generator
