Back to the Three Kingdoms and become a python

When he first moved to Wanghai, Lin Bei actually wanted to develop electricity. He even asked An Zhong to find a place with a huge sea breeze, and planned to generate wind power. Later, Lin Bei felt that this matter was not reliable, and he also It didn't continue.

Everyone in modern times knows about electricity, but about how electricity comes from, I am afraid that many people, except professionals, will not know. The job of generating electricity is not something everyone can do.

Lin Bei happened to know a little bit, because when he was in middle school, Lin Bei was good at physics, including the principle experiment of power generation.

An iron ring, if a bar-shaped magnet passes through the middle, the iron ring on the iron ring will make a movement of cutting the magnetic induction line, and a current will be generated on the iron ring, and this is the simplest principle of power generation. Although it is weak, there is indeed electricity on it. This is also a simple generator, but Lin Bei has never done it.

But is this enough?Obviously, this is not enough, we need to store electricity. As for how to store it, well, Lin Bei only knows about batteries. As for how batteries are made, I am sorry that Lin Bei is not serious about his study, anyway, he can't think about it at all. Wake up, vaguely remember lithium in it?Don't all mobile phones pay attention to lithium batteries?

Anyway, Lin Bei doesn't know how to store electricity, and Lin Bei only knows so much about power generation. He really knows a little bit, and the rest has to be left to Huang Yueying and the craftsmen to perfect.

Lin Bei immediately explained the principle of power generation, which is the iron ring of the magnet. Huang Yueying nodded: "My lord. Then what then?"

"And then it's gone..."

"Uh, so that creates that... electricity?"

"Yes, although this electricity is not as powerful as lightning, it is indeed electricity."

"My lord, it sounds very simple." Huang Yueying said very easily.

"Well, it's really simple. I like you, Yueying will definitely not let me down."

Huang Yueying looked at Lin Bei suspiciously, but she carefully recalled Lin Bei's words just now, and she really couldn't think of any difficulties. Wanghai City has magnets, and iron rings are also very easy. Just wind some wire and it's over. ?Even a blacksmith can make it, is there any difficulty in that?

Lin Bei said slowly again: "Yueying. My lord may as well tell you that it is very simple to make electricity, but do you know what electricity is?"

"Isn't it the kind like lightning?"

"Electricity is an invisible thing. It has no weight and can only be felt. Electricity with low power will only make people's fingertips numb. This kind of electricity has no effect. What you have to do is to produce a high-power current. In this way Well, let me set a goal for you. As long as the electricity you make can light up like a candlestick, it will be considered a success."

"Illuminate like a candlestick? My lord, didn't you say that electricity is invisible? How can it be illuminated?"

"Then I don't care. Anyway, I know a magical thing called an electric light. As long as there is electricity, the electric light can light up. As long as you can make the electricity light up. Yes, light up like lightning, then that's fine." Lin Bei dug a big hole for Huang Yueying.

"Then Yueying will try it." Huang Yueying didn't know how difficult this matter was. She could be regarded as a scientific researcher, and she was quite interested in this kind of research.So I agreed with one bite.

"Well, don't let my lord down."

Seeing Huang Yueying walking out excitedly, to be honest, Lin Bei didn't hold out too much hope, because there are no materials in this era, electric lights?There are tungsten filaments in it, and the bulb is a vacuum. These two are difficult to make with the current level of technology, but think again, never underestimate the wisdom of working people, sometimes you clearly think they can't do it , but they can really surprise people.

But what Lin Bei didn't expect was that the surprise would come so quickly.

Huang Yueying went to make electricity, so Lin Bei called An Zhongzhi and told An Zhongzhi not to open the steam engine for the time being, unless he found another kind of kinetic energy that could replace the steam engine, that is, the electricity that Lin Bei thought of, and when the electricity was almost perfected , Lin Bei will gradually open up the steam engine so that the people can also buy it.

Although An Zhongzhi supported the opening of the steam engine, since Lord Dragon God said so, it meant that it was the final decision, and An Zhongzhi could only follow it, and asked about Mancheng's reply.

The yellow scarves and common people captured from Anding County last time were not in a state of mind. Cui Lan suggested that Lin Bei should go to Xinmancheng to see if Mancheng could send their families here. It has been more than half a month now. Zhong Zhi just came to ask if there is any news,

Lin Bei shook his head and said, "No, there is no news from Man City. This incident is probably enough. Are those people still like this?"

"Although he has settled down a lot, Zhongzhi is a little uneasy after all."

If these people's family members are all dead and it's okay, they won't worry about it, and now their hearts will indeed fluctuate, even if Wanghai City is better than Man City, because these people's homes are not here.

"It's not a problem to keep procrastinating."

An Zhongzhi nodded and made a suggestion: "Sir, why not? Let's exchange people with Mancheng, send half of the people back to Mancheng, and let the big man bring the other half of his family. What do you think?"

"Half and half? Yes, as long as these people can settle down, this matter is up to you to arrange. In addition, common people can change more, and women can also change more."

"Zhongzhi understands."

At dinner in the evening, when Lin Bei, An Zhongzhi and the others were discussing the details of land sharing, Huang Yueying stepped into the city lord's mansion and shouted loudly: "My lord, Yueying has already created electricity, and it can also be turned on. "

Lin Bei froze for a moment, "How is it possible, Yueying, when will you learn to lie."

"My lord, I don't have it. I really created electricity, and it can really turn on."

"It's really bright?" Lin Bei still didn't believe it.

The inside of the light bulb is tungsten filament, and the inside is a vacuum. Huang Yueying can make a light bulb in just half a day?Even if Huang Yueying is 1 times smarter than Edison, it is impossible to create it due to the technological level of this era.So Lin Bei is [-] unbelievers.

"It's really bright. It's very simple. Yueying made electricity according to what the adults said, and the wires lit up immediately." Huang Yueying's expression was still unfinished, and she looked very relaxed.

"Then take my lord to have a look." Lin Bei was really surprised.

At the moment, Lin Bei stopped discussing matters.Taking An Zhongzhi and following Huang Yueying, the two rode bicycles, Lin Bei walked, and rushed towards the craftsman's workshop. They entered a room in the workshop, and Huang Yueying opened the door.

There were several craftsman apprentices in the room, Huang Yueying shouted to these people: "My lord is here, just wait and start pushing."

These apprentices agreed.Then push a pillar-like thing, which is a huge bar magnet, piled up and pulled together, and something beside it lit up, Huang Yueying pointed there and said: "Look, my lord, Isn't it just bright?"

Lin Bei couldn't speak for a moment, did it really light up?This is too simple, right?It wasn't a light bulb at all, but a length of wire glowing.

Take a closer look at the generator again.It was done according to what Lin Bei said, and the iron was made into a barrel shape.A large bundle of thick iron wires was wrapped around the outside, and bar magnets could pass through the cylinder, pushed and pulled on both sides, and then looking at the flickering place, Lin Bei suddenly realized that it was so.

Originally, the wires were connected together.It is in a short circuit state. If the current is continuous, the iron wire will be blown, but because the magnet is in the process of pushing and pulling, the iron wire will not be blown immediately.But it will be like this flickering state, which can be regarded as really bright.

Huang Yueying said excitedly: "My lord, I tried it just now. When I touched the iron wire, it was really numb. This electricity is really miraculous, it can actually make the iron wire glow."

"Cut the wire and have a look again."

Huang Yueying obeyed and asked the craftsman to cut off the iron wire, and then pushed and pulled the magnet again. This time, the iron wire did not emit light because they were not in contact with each other.

"Huh?" Huang Yueying was surprised.

"You don't understand?" Lin Bei asked.

Huang Yueying shook her head: "My lord, why is this?"

Lin Bei was speechless. This Huang Yueying was just a mistake, but she actually made a simple generator. Huang Yueying didn't quite understand it, but it made Lin Bei understand something. It turns out that this kind of generator can really generate electricity. .

So Lin Bei became a teacher for a while, and carefully explained the principle of luminescence, that is, the connection between resistance and current, through this real object. Through the narration, he also slowly recalled some things, which can be said to be a review of the past. Learn new things.

That section of wire flashed and flashed for several hours, then the wire suddenly snapped and broke into two pieces. The wire was burnt.

But despite this, Lin Bei understood one thing, that is, it is not necessary to use tungsten wire as the wick in the bulb. In fact, other things are also fine. For a long time, it can be replaced by other things, but the frequency of replacement is higher. At first he thought that Huang Yueying couldn't get it out. It was Lin Bei who made things complicated. It doesn't necessarily need a light bulb to light up...

"Yueying, do you think this kind of electricity can be used in my Wanghai City?"

"My lord, of course it's possible, and it doesn't need manpower, isn't it just to keep the magnet moving? My lord, I can do this." Huang Yueying said with certainty, she can even make wooden cows and horses. Of course it won't trouble her, but Huang Yueying then said: "My lord, although this electricity is miraculous, but from Yueying's point of view, it can only be used for lighting at night, it is far worse than that steam engine."

Lin Bei smiled: "Yueying, you can only see electric lighting now, but if you think about it again, it is also electricity, so why can lightning split people into coke? When I start building steam engines, I can't take it with me." Driving a horse-drawn carriage, but later it can make the carriage travel thousands of miles a day, this electricity has the potential not inferior to the steam engine, if it is really used well, it is even more wonderful than the steam engine.”

Huang Yueying frowned, and then nodded lightly, "It seems that this electricity has a lot to do. Don't we need to enlarge the iron ring and magnet several times? Then the current will be even bigger?"

"This is one method, but there must be other methods, and Yueying needs to do this."
