Electricity is a good thing, and no one living in the 21st century can live without electricity.

Lin Bei has traveled to this era for almost two years, and he is still a little unaccustomed to life without electricity, especially when he comes out at night, it is pitch black, and it is very unpleasant to think about it.

When he first moved to Wanghai, Lin Bei actually wanted to develop electricity, and he also asked An Zhongzhi to find a place with a huge sea breeze and prepare for a wind power generation, and then Lin Bei felt that this matter was not very reliable, so he did not continue.

Modern people know about electricity, but as for how electricity comes from, I'm afraid that many people will not know except professionals, and not everyone can do the job of generating electricity.

Lin Bei happened to know a little bit, because when he was in middle school, Lin Bei's physics was very good, and there was the principle of power generation.

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

But is that enough? Obviously, this is not enough, you have to store the electricity, as for how to save it, okay, Lin Bei only knows the battery, as for how the battery is made, forgive Lin Bei for not studying seriously, anyway, he can't remember it at all, vaguely remember that it is lithium? Don't you pay attention to lithium batteries in mobile phones?

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

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

"And then it's gone."

"Uh, so you can make that electricity?"

"By the way, although this electricity is not as powerful as lightning, it is indeed electricity."

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

"Well, it's really simple. I'm optimistic about you, Yueying will definitely not disappoint Lord Ben. ”

Huang Yueying glanced at Lin Bei suspiciously, but she carefully recalled Lin Bei's words just now, and really couldn't think of any difficulties, magnets, Wanghai City has them, and the iron ring is also very easy, isn't it over just a little wire? It's a blacksmith who can make it, so what's so hard about it?

Lin Bei said slowly: "Yueying." I might as well tell you that it's easy to get electricity, but do you know what electricity is? ”

"Isn't it the lightning-like kind?"

"Electricity is an invisible thing, it has no weight, it can only be felt, and the electricity with low power will only make people's fingertips tingle, this kind of electricity has no effect, all you have to do is make a high-power current. Well, set a goal for you. As long as the electricity you make can light up like a candlestick, you are successful. ”

"Shine like a candlestick? Didn't you say that electricity can't be seen, my lord? So how can it be illuminated? ”

"Then I don't care, anyway, I know a magical thing, called electric light, as long as there is electricity, the light can be lit, you just need to make the electricity light up. Yes, if it lights up like lightning, that's fine. Lin Bei dug a big pit 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 research worker, and she was quite interested in this kind of research thing. So I agreed in one bite.

"Well, don't let Ben-sama down."

Seeing Huang Yueying rushing out, to be honest, Lin Bei didn't have much hope, because there are no materials in this era, electric lights? There is tungsten filament in it, and the light bulb is vacuum, these two are difficult to get out with the current level of technology, but then think about it, never underestimate the wisdom of working people, sometimes you obviously think they can't do it, but they can really surprise people.

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

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

Although An Zhongzhi supports the opening of the steam engine, since Lord Ryujin said so, it means that it is the final decision, and An Zhongzhi can only comply, and asks about the reply from the barbarian city.

Didn't the yellow turbans and common people who were caught from Anding County last time have their minds floating, Cui Lanjian asked Lin Bei to go to Mancheng to see if he could let Mancheng send these people's families, and now it's been more than half a month, and An Zhongzhi is just here to ask if there is any news.

Lin Bei shook his head and said: "No, there is no news from the barbarian city, this matter is estimated to be enough, are those people still like this now?" ”

"Although I have settled down a lot, I am a little uneasy after all."

If all these people's families are dead, they won't worry, and now they will indeed have people's hearts fluctuating, even if Wanghai City is better than Barbarian City, because these people's homes are not here.

"It's not a problem to drag it out like this."

An Zhongzhi nodded and made an opinion: "My lord, why don't you do this?" Let's exchange people with the barbarian city, send half of the people back to the barbarian city, and let the big barbarian send the other half of the family, what do you think? ”

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

"I understand."

At dinner in the evening, when Lin Bei, An Zhongzhi and others were discussing the details of Juntian's production division, Huang Yueying stepped into the city lord's mansion and shouted loudly: "My lord, Yueying has already made electricity, and it can also make electricity bright." ”

Lin Beileng paused, "How is it possible, Yueying, when will you also learn to deceive people." ”

"My lord, I didn't, I really made electricity, and it really lit up."

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

The inside of the bulb is tungsten filament, and inside is a vacuum, and it only takes half a day for Huang Yueying to make a bulb? Even if Huang Yueying is 10,000 times smarter than Edison, given the level of science and technology in this era, it is impossible to create it. So Lin Bei is 10,000 unbelievers.

"It's really bright, it's very simple, Yueying made electricity according to what the adults said, and the wire lit up at once." Huang Yueying's face was still unfinished, and she looked very relaxed.

"Then take Ben-sama to have a look." Lin Bei was really weird.

At the moment, Lin Bei is no longer discussing. With An Zhongzhi and following behind Huang Yueying, the two rode bicycles, Lin Bei walked, rushed towards the craftsman's workshop, and entered a room in the workshop, Huang Yueying pushed the door open.

There were a few apprentices in the house, and Huang Yueying shouted to these people: "My lord is here, you can start pushing." ”

The apprentices agreed. Then push a pillar-like thing, this is a huge strip magnet, a pile of pulls, there are things on the side that flash and light up, Huang Yueying pointed there and said, "Look, my lord, isn't it just lit?" ”

Lin Bei couldn't speak for a while, but it really lit up? That's too easy, right? It's not a light bulb at all, it's just a wire glowing.

Take a closer look at the power generation unit again. It was made according to what Lin Bei said, and the iron was made into a barrel shape. There was a thick bundle of iron wire wrapped around the outside, and the bar magnet could pass through the cylinder, pushing and pulling on both sides, and then looking at the flashing place, Lin Bei suddenly understood, so it was.

Originally, the wires were connected. If the current is continuous, the wire will be burned, but because the magnet is in the process of pushing and pulling, the wire will not be burned immediately. It's like this state of flashing and flashing, and it's really bright.

Huang Yueying said with some excitement: "My lord, I tried it just now, and when I touched the wire, it was really numb, this electricity is really magical, it can actually make the wire glow." ”

"Cut off the wire and take another look."

Huang Yueying obeyed, asked the craftsman to cut off the wire, and then pushed and pulled the magnet again, this time, the wire did not shine because they did not touch 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 it was really made into a simple generator, Huang Yueying didn't understand it very well, but it made Lin Bei understand something, it turned out that this kind of generator can really generate electricity.

Lin Bei then became a teacher, and carefully explained the principle of luminescence through this object, that is, the connection between resistance and current.

The wire flashed and flashed, and after flashing for a few hours, the wire suddenly snapped and broke into two, which was a positive and negative electrode hedge, and the wire finally couldn't withstand this energy, so it formed a short circuit and burned out the wire.

But despite this, Lin Bei understands one thing, that is, it is not necessary to use tungsten filament as the wick in the bulb, in fact, other things can also be used, tungsten filament just makes the life of the bulb longer, it can always be lit for a long time, and it can be replaced by other things, but the frequency of replacement is greater, at first he thought that Huang Yueying couldn't get it, it was Lin Bei who thought about things complicated, and it was not necessary to need a bulb to light it up

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

"My lord, of course you can, and you can do it without manpower, don't you just make the magnet keep moving? My lord, I can do that. Huang Yueying affirmed that she could even make wooden oxen and flowing horses, which of course did not bother her, but Huang Yueying then said: "My lord, although this electricity is magical, but in Yueying's opinion, it can only be used for lighting at night, which is far worse than the steam engine." ”

Lin Bei smiled: "Yueying, you can really only see electric energy lighting now, but if you think about it again, it is also electricity, why can lightning split people into coke, when I started to build a steam engine, I couldn't bring a carriage, but later it could make the carriage travel thousands of miles a day, this electricity has the potential to be not inferior to the steam engine, it is really used well, it is more wonderful than the steam engine." ”

Huang Yueying frowned, and then nodded slightly, "In this way, this electricity is promising, do you need to magnify this iron ring and magnet several times?" And then the current will also be greater? ”

"This is a method, but there must be other methods, and this needs to be done by Yueying."

"Adults really know Yueying, Yueying, this is what I love to do the most." Huang Yueying said happily.

"Okay, in addition, you first install a generator for the City Lord's Mansion, Lord Ben has always been thinking about electricity." Lin Bei really imagined the days when there was electricity. (To be continued......)
