Chapter 733: Ban Heng: As A Science Sage, It Is Reasonable To Rub The Generator By Hand [Please Subs
After hearing Yan Changqing talk about his research on thunder and lightning, Zhu Yuanzhang finally understood the reason why Yan Changqing took Lu Wenzhao, Pei Lun and other royal guards to fly kites on rainy days with thunder and lightning from time to time last year.
Although Lu Wenzhao and Pei Lun also asked Yan Changqing what he was doing at that time, Yan Changqing just replied that he was doing research, but did not say more.
Therefore, Zhu Yuanzhang did not know that Yan Changqing was doing research on thunder and lightning at the time, if he had known.
Then maybe Zhu Yuanzhang will ask a few more questions. After all, studying thunder and lightning is very cool when you hear it.
Of course, it's not that Yan Changqing doesn't want to say it. The main reason is that many times Yan Changqing says it, and Lu Wenzhao, Pei Lun and other Jinyiwei can't understand it, or even Zhu Yuanzhang who receives the report can't understand it.
So most of the time, if Yan Changqing didn't take the initiative to talk, they wouldn't take the initiative to inquire in depth.
After all, once they asked in depth, Yan Changqing explained to them enthusiastically, but in the end they showed a clear and stupid look, which would be very embarrassing.
Even someone like Pei Lun, who has a high sense of morality, will feel guilty because of this.
After all, Saint personally answered their questions and answered their questions. How many people couldn't ask for such an opportunity even if their ancestral graves were smoking.
However, they got the opportunity for Saint to answer questions in person, but in the end they were too stupid to understand. Is this Saint's problem?!!
Of course it's not Saint's problem, it's obviously my own problem!!!
It’s me who failed Saint’s expectations!
I wasted the opportunity that millions of people dream of!!
It is you who wasted the opportunity that the smoke from your ancestral grave brought to you!!!
In this case, if you were a person with a higher sense of morality, would you still be able to eat at night?!!
Obviously, Lun is such a person with a relatively high moral sense.
Maybe it wasn't before, but I don't know if it's because I've been with Yan Changqing for a long time, or if it's been a long time since I did the kind of work that Jin Yiwei did before, like killing people, setting fires, ransacking homes, genocide, extorting confessions, etc.
Now Pei Lun's own moral level is getting higher and higher, and at the same time, his requirements for himself are becoming more and more strict.
You can often see Pei Lun, in addition to handling the work assigned to him by Yan Changqing, holding various books compiled by Yan Changqing, or books that Yan Changqing mentioned that he thought were worth reading. look.
After years of accumulation, it is no exaggeration to say that Pei Lun is the most knowledgeable and memorized among all the Jinyi guards, and has the highest level of knowledge and culture.
It's just that Pei Lun is relatively low-key, so few people know about it.
But then again, the various scientific experiments conducted by Yan Changqing in the past were not actually to verify anything, but just for the verification process.
Because the results of the verification had already been obtained and proven in his previous life, there was no need for him to repeat the verification.
But the reason why he went to the trouble of repeating the verification was mainly to let the world know how his results came from.
Just like "friction generates electricity", he doesn't need to do the "friction generates electricity" experiment anymore, he also knows that static electricity will be generated through friction.
But others don't know, so he needs to do this "triboelectricity" experiment again in front of others.
Then he came up with the conclusion of "friction generates electricity" to let others know: "Oh, so this is how static electricity comes from!"
After all, there is no experimental process, and conclusions can be drawn directly from "mental simulation experiments". If possible, it is better to do less.
Perhaps people in the current era, due to their insufficient knowledge and culture, are not able to understand the value of "without actual experiments, simulating experiments directly from their minds, and the results are completely correct" .
However, if it is passed down to future generations, they may regard him as some kind of "alien", "monster", "pervert" or "inhuman" existence.
Tsk tsk tsk, if possible, he still wants to retain his "human status" as much as possible and be treated as a normal person by future generations.
Song Lian on the side, after listening to Saint Ban Heng's talk about frictional electricity, couldn't help but ask:
"Wait a minute, Saint, you said that you have a preliminary understanding of the causes of thunder and lightning in nature. May I ask what causes this?!!"
Song Lian looked at the Science Saint Ban Heng with a puzzled face. Did he miss something just now?!!
How did Kesheng Banheng understand the causes of thunder and lightning in nature through "frictional electricity"?!!
Is there any necessary relationship between "frictional electricity" and "the cause of natural lightning"?!!
Why can't he figure out at all, is there such a big gap between Saint and other people?!!
Yan Changqing looked at Song Lian and said in a gentle tone:
"The cause of natural lightning is inferred through some experiments after frictional electricity generation.
"Through triboelectricity experiments, I discovered the existence of electric charges, which are divided into positive charges and negative charges."
"When positive charges rub against negative charges, weight occurs."
"Essentially, the principles of natural lightning generation and 'frictional electricity generation' are the same."
"Thunder and lightning is a discharge phenomenon in the atmosphere, mostly produced in cumulonimbus clouds. During the formation of cumulonimbus clouds, some clouds are positively charged and some are negatively charged."
"Their electrostatic induction of the earth causes opposite charges to be generated on the ground or on the surface of buildings. When the charges accumulate to a certain extent, the voltage will reach an extremely high level.
“When the electric field between clouds of different charges, or between clouds and the earth, is strong enough to penetrate the air, dissociation discharge will begin, which I call ‘pioneer discharge’.
"During the discharge, when a strong current passes through the air, it will cause the air along the way to suddenly expand and push the surrounding air, causing the air to vibrate violently.
The sound produced at this time is thunder. "
"The leader discharge from the cloud to the ground develops gradually from the cloud to the ground. When it reaches the ground (buildings on the ground, etc.), a reverse main discharge from the ground to the cloud will be generated."
"During the main discharge stage, due to the violent neutralization of opposite charges, a large lightning current will appear, followed by strong lightning and loud noises, eventually forming the lightning we see in nature."
Listening to the narration of Science Saint Ban Heng, Song Lian nodded with a look of understanding.
Although he didn't fully understand it, at least he understood a little bit, that is, friction generates electricity. Nature's lightning is also generated by the friction of positive and negative charges.
Weird knowledge added to Song Lian's gains.JPG
"Based on this phenomenon, we can make lightning rods, or lightning rods, to absorb lightning and guide lightning to the ground, thereby preventing lightning from destroying buildings."
"Of course, the so-called lightning rods and lightning rods have actually been around for a long time. Many people even have lightning rods and lightning rods installed in their homes."
"For example, at both ends of the roof of His Majesty's Palace, there is a dragon head that looks up. A twisted metal tongue spits out from the dragon's mouth and reaches into the sky. The base of the tongue is connected to a thin wire that goes straight to the ground."
"This is the lightning rod, the lightning rod!"
"When lightning occurs, if lightning hits the palace, the current will travel from the dragon's tongue to the ground, thus preventing the lightning from destroying the building.'
"After you go home, you can also see if there is anything similar to this device in your mansion."
"If there is, that's great; if not, you can consider asking a craftsman to help reinstall it."
Yan Changqing looked at all the civil and military officials and smiled.
After hearing the words of Kesheng Banheng, all the civil and military officials decided to go back and climb on the roof to see if there were such lightning rods and lightning rods installed on their mansions.
If not, you must find a craftsman to install one for your home later.
Yan Changqing looked at Zhu Yuanzhang and all the civil and military officials and continued:
"Although I have a preliminary understanding of the causes of lightning in nature, and a rough grasp of the methods of artificially generating electricity."
"But compared with the electricity generated by frictional electricity, there is a huge difference between the two and the real thunder and lightning in nature."
"Moreover, generating electricity through friction was still too laborious and clumsy after all, so I started looking for other ways to generate electricity more easily."
"In the end, I discovered another phenomenon, which I named - the phenomenon of electromagnetic induction, or the law of electromagnetic induction!!!"
"The so-called electromagnetic induction phenomenon refers to the phenomenon of induced electromotive force due to changes in magnetic flux."
"For example, when a part of a conductor in a closed circuit moves to cut the magnetic field lines in a magnetic field, a current will be generated in the conductor. I call the generated current an induced current, and the generated electromotive force (voltage) is called an induced electromotive force."
"Of course, this is not very important to you. It doesn't matter whether you understand it or not. This is mainly what scientists need to learn and understand in the future."
"Importantly, through the phenomenon of electromagnetic induction, we know that when a permanent magnet moves relative to a conductor (and vice versa), an electromotive force is generated."
"If the wire is connected to an electrical load, current will flow, thus generating electrical energy, converting the energy of mechanical motion into electrical energy.
"."And if we understand this, we can make a 'generator'!!!"
Having said this, Yan Changqing picked up the hand-operated generator that was about one foot long and half a foot high on the table and showed it to Zhu Yuanzhang and all the civil and military officials.
"What you see in front of you is the first-generation 'hand-cranked generator' made by my hands!!!"
"The hand-operated generator is mainly divided into five parts. The first part is made of permanent magnets as the stator, and the second part is made of conductors wrapped with copper wire coils as the rotor.
The third part is the hand turntable, the fourth part is the copper wire, and the fifth part is the electric light. "
"The conductor rotor is located inside the permanent magnet, and the conductor rotor and the hand turntable are pulled by a rope."
"According to the law of electromagnetic induction, when we shake the turntable by hand, the turntable will drive the conductor rotor to rotate rapidly through the rope."
"When the conductive rotor rotates rapidly, it creates relative motion with the permanent magnet outside, which causes the coil to continuously rotate in the magnetic field and cut the magnetic field, causing electromagnetic induction and generating current."
"Electrical current flows through wires, producing electrical energy."
"When electric energy passes through the carbonized bamboo filaments, it generates heat. The spiral filament continuously collects the heat, making the temperature of the carbonized bamboo filaments reach over 2000°C. When the carbonized bamboo filaments are in an incandescent state, they glow like red-hot iron. , thereby emitting light to illuminate the surroundings.”
"This is also the reason why I named the lamp an electric lamp, because this lamp is driven by electrical energy and converted into heat energy and light energy, thereby achieving luminescence.
As Yan Changqing narrated, he kept shaking the hand-cranked generator in his hand.
very
Quickly, the hand-cranked generator in Yan Changqing's hands generates electricity due to the law of electromagnetic induction, and is transmitted through wires to the small light bulb installed next to the turntable. Finally, the small electricity
The light bulb flickered on.
Seeing this scene, whether it was Zhu Yuanzhang, Empress Ma, or other civil and military officials, they were all stunned.
To be honest, they basically didn't understand what Yan Changqing said before.
But they understood the scene before them.
Just turn the dial and the little light bulb will light up!!!
No fire, no candles, no firewood, no briquettes, no methane, no oil, no natural gas, nothing can shine by itself!!!
What kind of magical trick is this?!!
After cranking the generator for a while, Yan Changqing stopped.
After all, if you want to generate electricity, the speed of the conductor rotor must not be slow, so after shaking the generator for a while, Yan Changqing felt his hands sore.
Then looking at Zhu Yuanzhang who was full of curiosity and eager to try, Yan Changqing smiled and then handed over the hand-cranked generator.
Zhu Yuanzhang was not polite when he took over the hand-cranked generator, and immediately followed Yan Changqing's actions just now and started to turn it on quickly.
All the civil and military officials who were watching couldn't help but exclaimed:
"It's light! It's light! It's light again!"
"Hiss, is this the 'Law of Electromagnetic Induction'?!!"
"As long as it keeps spinning, electricity can be generated, and then the lamp can be lit.
“If that’s the case, wouldn’t there be no need to light candles at night anymore?!”
"The light emitted by this electric lamp is much brighter than a candle. It is almost like daylight."
"Saint's methods are truly incredible, simply unbelievable!"
