The working light of the ballast is on......

Electricity, generated.

Looking at the pointer beating above, the current passes through the ballast, becomes smooth, and the wattage also becomes 220V for household electricity.

The size of the magnet, Li Chu has studied it carefully, it is too small, the number of V produced is insufficient, too big and too strong, he can only touch it reluctantly, plus the role of the ballast, in order to stabilize the current at this value.

This place, usually no one should come in and mess around.

However, tomorrow you still have to add a door to lock it to be safe.

Maybe because of the rain last night, the sky is still gloomy, I can't see a little moonlight, and this night is even darker, touching the night, Li Chu returned to the small courtyard.

Yang Cheng, Yang Kang and A Ning couldn't wait to clamore for a long time.

Yang Cheng is the most mischievous, if it weren't for Ah Xiu to stop him, he would have to climb the stairs and go up to touch the wires and light bulbs.

In the hall, small oil lamps were burning.

Li Chu first turned on the main switch in the room, and then reached out to the closed circuit switch by the door with his left hand.

He didn't press it the first time.

For the time and space of the Northern Song Dynasty, the next moment is about to usher in a new light.

This is an epoch-making time in the Northern Song Dynasty, and it is also an epoch-making time point for all mankind in this time and space.

Although there are some suspicions of cheating, it is a great action to be able to show electricity more than 600 years in advance.

Under the watchful expectations of Yang Cheng, Yang Kang, A Xiu, and A Ning, and under the light of the thunder and lightning above the sky, Li Chu pressed the switch.

Syllable......

Between heaven and earth, it was bright in an instant.

In the courtyard, Yang Cheng, Yang Kang, A Xiu, and A Ning closed their eyes one after another, and the strong light came so unexpectedly, so unexpectedly, and so unexpectedly.

After a long while, Ah Xiu slowly opened his eyes, put his hand on his eyes, and looked at the light like day around him in a daze.

Everyone was so shocked by this brightness that they couldn't say a word.

Even the most innocent A-Ning was tilting his head at the moment, looking at the incandescent lamp above his head stupidly.

This......

Isn't it night, why is it so bright, brighter than the day?

Ah Xiu looked around the room stupidly, couldn't believe it, and even pinched his arm, thinking that he was dreaming.

It hurts.

Ah Xiu turned around and looked out of the house, it was pitch black......

Then he turned around and looked into the house, which was brighter than daylight......

Turn around again, turn back again, turn back again, turn back again......

Ah Xiu seems to have discovered that this light seems to be emitted by something, and this thing can't be seen clearly, it's too dazzling, but this location, isn't it just now that Li Chu put it on it, a fairy thing called an incandescent lamp?

Li Chu smiled, patted the heads of Yang Cheng, Yang Kang, and A Ning, and said, "Don't be stupid, go to the yard, take a look." ”

What I turned on just now was the switch in the hall.

Now Li Chu turned on the incandescent light switch in the yard again.

Syllable......

Although the incandescent lights installed in the yard are brighter, because it is night outside, the range of light propagation and darkness is too large, but it is not as bright as the house.

It wasn't until this moment that Ah Xiu and the others came to their senses, it turned out that this was Li Chu's trick.

Electricity, after all, is a dangerous thing, and if it is used well, it is a killing weapon for the benefit of the people and the country, and if it is not controlled well, it will bring disaster.

Therefore, Li Chu wants to take advantage of the present to give the four of his family a good lesson on electricity.

"What you see now, this thing that emits light like daylight, is called an incandescent lamp, and it itself does not become so bright, because there is an energy injected into it, and this energy is called electricity.

This electricity is actually one of the immortal methods, called the thunder method......"

In order to better let the four of them understand the meaning of electricity, Li Chu had no choice but to interpret it as a kind of immortal law, and when they learned physics later, they would be able to understand the meaning.

So far, Li Chu can only use the guise of immortal law to warn them not to touch or touch it with their hands, otherwise they will be struck and killed by Lei Fa Tianning, especially the small house on the bank of the river, which is the site for collecting Lei Fa, don't go.

Of course, sometimes the more you don't let go, the more curiosity you get.

But everyone still understands this thunder method, because there are always thunder and lightning flashes on rainy days, and there are more than one or two examples of lightning strikes hurting people and damaging houses.

Therefore, Li Chu's admonition still played a role, at least for now, looking at their nervous faces, Li Chu had no choice but to shake his head and smile, and how to use the method of lighting the lamp was demonstrated in front of the four people.

After knowing that there was this incandescent lamp in every room, Yang Cheng and A Ning ran to the room where they were sleeping and found the switch at the door.

Syllable.

The rooms on the left and right were also brightened.

……

In the small courtyard, Yang Cheng, Yang Kang and A Ning kept cheering, and Ah Xiu also stared at Li Chu with a smile.

For Yang Cheng, in the future, he can also practice the Yang family gun in the yard at night.

For Yang Kang, he will be able to read and write in the house at night as he does during the day.

For A-Ning, you don't have to go to bed so late at night in the future......

Li Chu shook his head.

For this generator, counting the consumption of cement before, etc., the forty-five custom coins obtained the day before yesterday are now only seven.

There are only seven customization coins left, and this new task has to be stepped up.

In the yard, the three little ones were chasing and fighting, in fact, tonight was no different from usual, the only difference was that the night was much brighter and the lighting was provided.

Electricity is just one of the foundations of nightlife.

In the future, there will be countless household appliances and the like, and by that time, electricity will be the top priority.

Li Chu checked it in the customization system, and sure enough, as he guessed, after making a small generator by himself, the technological barriers in the customization system were broken, and the customization price of the generator dropped wildly.

From the beginning of 100,000 custom coins, now only 500 custom coins are sold.

This price drop is really terrifying.

However, not all generator prices have fallen, but the price of types of generators under the existing technology has declined.

While Li Chu was pondering, the quiet night was broken by a hint of noise.

Close your eyes and listen carefully, there are a lot of people talking, very noisy, and the noise is getting louder and louder, as if it is coming this way.

I heard it, it seems that someone is shouting to catch a youkai......

Monsters, monsters?

Ancient society, and youkai?

Just about to mock this group of ignorant people, Li Chu was suddenly stunned.

Something is wrong.

Damn, this group of people is coming for themselves!

Electricity, light up!

It must have been the electric light that drew the crowd over.

Li Chu sighed self-deprecatingly, although this courtyard is not far from the village, but on this big night, the speed of light propagation is particularly far, and there is also a small village on the other side of the river.

Youkai, hah.

The sound was getting closer, and there were many footsteps.

Li Chu walked to the gate of the courtyard, opened the door, and sure enough, saw Li Han rushing over with a group of people with sticks in their hands.

There are men and women, old and young, all of whom are villagers in Lijia Village, who are the closest to this place and are the first to discover the strange scene here.

Li Han, the uncle, got a high salary on Li Chu's side today, and Li Chu hired them in a few days, so he was very concerned about this side, and when he saw this situation, he immediately called someone to come and save people.

"Good evening, uncles and uncles."

Li Chu was outside the courtyard, beckoning to them with a smile, this group of people stopped outside the courtyard quite unexpectedly, and after looking at Li Chu who was unharmed, Li Han breathed a sigh of relief and asked, "Xiao Chu, are you okay?" What's going on in your yard, how can it be as bright as daylight? ”

"It's just a trick, uncles and uncles, please come in and see it."

Li Chu's invitation, many people in the crowd stopped, obviously frightened by this beyond the concept.

But there are also some bold people, such as Li Han, without saying a word, he was the first to come in, and behind him, he also followed a group of bold people one after another, and the people behind him were afraid, but when they saw that everyone came in, they had to follow in.

In the courtyard, Ah Xiu led the three little ones to occupy the door of the hall.

There were too many people coming, so Li Chu couldn't invite everyone into the house, so he demonstrated the electric light to everyone in the courtyard.

As for the statement, he made a small modification here, unlike Ah Xiu, he omitted the immortal here, and said that he had been inherited by the public loser, and he was the successor of the new Lu craftsman, and this electric lamp was just a new craft passed down by the Lu craftsman.

This afternoon, I asked Li Han and a few people to help, and this is to make this.

As soon as they said this, Li Han and the other ten people suddenly realized that this was the case.

Li Chu said that while demonstrating, he also invited a few old people with more prestige in the village to open and close the switch in person.

So, the incandescent lights in the yard turned on, turned on all at once, turned on at once, turned off again, and then was turned on again, and the old man who was playing with the switch couldn't close his mouth with a smile.

After knowing that it was not the devil and the monster, but the skill of the craftsman Lu, everyone was surprised and novel.

"Oh, if this night is like day, then I can do a lot more work."

"Yes, yes, today is a long experience, it turns out that there is a lamp as bright as day, it is too novel, this is much brighter than the oil lamp, much more comfortable."

"Xiao Chu, is this thing easy to get, is it expensive, can you put a few in the village?"

The one who asked this was the old man who played with the switch just now.

"In the future, this thing can supply too little electricity now, and there is a bit of distance between this side of the village, and when I earn more money in the future, I can change to a better one, and then I can connect every household in the village to electricity!"

What Li Chu said was honest, but now his situation is really impossible.

"Xiao Chu has a heart, with your words, everyone in the village will be comfortable."

"Xiao Chu is really a good boy, he is really filial, he has good things, and he will not forget the uncles and uncles in the village, good, good."
