Otaku Engineer in Great Tang Dynasty Chapter 1448: Electric meter and triode! (Come on, college entrance examination students!)

"Don't squeeze! Come one by one, line up, everyone will definitely be in line today~!"

Lantian County, Yanhuang Bank.

When the common people learned that the Lantian County bank exchanges Tang Yuan without commission, saves money and can still get interest, they all swarmed with most of the copper coins at home. At this time, the sun is rising and the bank has just opened for business. , The front door was already full of people, and the small servants in the bank hurriedly came out to maintain order and calm the excited hearts of the people!

After all, these people are all carrying a large bag of copper coins. If there is a dispute because of the line problem, it is easy to lose money. Considering this situation, Li Ke hurriedly sent someone to notify the Lantian county government office. The government officials, let them come to maintain law and order here.

But there are still too many people who come to save money, there are thousands of people! Although the streets of Lantian County are not narrow after being renovated, they still cannot hold so many people!

The whole street in front of the Qianzhuang’s gate has been completely filled!

"With so many of us, will the bank stop accepting our money when it is our turn?"

"Yes! With so much money, it is impossible for the bank to collect all of it, right?"

Some people in the back row couldn't help but look worried.

The young man was obviously trained before, and he said loudly after hearing the words: "The folks can rest assured, since Lord Hou dares to save money and earn interest, our bank will definitely be able to eat the money saved by everyone, and we We will be able to guarantee the safety of your deposits! If you have something to do today and can’t wait, just go ahead and wait until there are fewer people to deposit. Our bank will accept it correctly! I promise you this!"

The words of Xiao Si, let the people feel a little at ease. Those people who are very low in the rankings are ready to go home with a copper purse. After all, people have a lot of farm work to do at home this season.

But there are still some big players in the team who are still uneasy and questioned: "You promise? You guys, what kind of guarantee? If everyone listens to you and go back now, what if the bank does not accept it tomorrow? What do you use to compensate us for our losses?"

As soon as the voice fell, there was a sparse echo from the crowd: "Yes! What guarantee do you have as a young man? Who will pay for our losses then?"

"Yes! Can't go back! Today, the old lady must deposit all the copper coins in Yanhuang Bank~!"

"Yes, yes! Don't go!"

After such a fuss, the people who were preparing to go home immediately stopped.

The little boy who shouted just now, seeing this scene, couldn't help but flushed with anxiety, but in this case, even if he said more, it won't help, because he is just a small servant of the money house!

"His guarantee is useless, what about mine?"

At this moment, a teenager walked out of the lobby of the bank and said blankly.

Although his voice is not loud, it just happens to reach everyone's ears clearly.

"Who is this young man?"

"Shut up! That is His Royal Highness King Shu!"

"What? It turned out to be His Royal Highness King Wu?"

Soon, someone recognized Li Ke, and the chaos and turmoil instantly calmed down.

"Since the folks recognize this king, then this king will explain some things in front of you today!"

Li Ke looked at everyone and said loudly: "No commissions, deposits and interest earned. This is a preferential policy launched by Yanhuang Bank of Lantian County for all the people in our county. This policy is long-term and absolutely not It will be there today and it will be gone tomorrow. In the name of King Shu, I promise you~!"

"His Royal Highness is wise~!"

"Your Highness is mighty~!"

After listening to Li Ke's vowed guarantee, the people suddenly burst into cheers.

After a while, the cheers faded away, and Li Ke went on to say: "In addition, I need to explain to you in advance that Yanhuang Bank’s deposit interest rate is not permanent. This month’s event is 1.75%. It may increase to 1.8% or 1.9% in a month, but it may also decrease to 1.7%. It may increase or decrease.

But this king can assure you that even if the deposit interest rate drops, it cannot be lower than 1.6%, so you don’t have to be in a hurry to come to the bank to save money today. When you have time, you can save money again. ! And maybe the interest will be more then, and you will get more money! "

"What? Deposit interest rates may go up?"

"My dear! Can any of you help me with the calculations. If the interest rate is 1.9, how much interest can I get for a year of deposit of 100 pennies?"

"Master, a hundred guan deposits can earn one thousand and fifty liters a year! Nearly two stats of money!"

"Haha! Okay! Those five hundred cans are ten dollars! Let's go! There are so many people today, let's not rush to save money with everyone!"

"Yeah! Don't rush to save money, I have to go to the mountain today to water Bai Diezi!"

"Right right! Wait for some day to spare before saving money!"

Listening to what Li Ke said, the people who were at the bottom of the line, whether they were big families or ordinary people, turned around one by one and left, but those at the top of the line didn’t leave much, because afterwards The deposit interest rate may increase, but it may also decrease at the same time! It would be better to deposit the money in the bank today with peace of mind!

Seeing that a large part of the people had finally dispersed, Li Ke couldn't help but breathe a sigh of relief. This can't be blamed on the small size of Yanhuang Bank. It is true that the flow of people just now was too large and scary, even though the size of the bank If you multiply it tenfold, it will be overwhelming!

This is the same as modern banks. If any bank branch welcomes thousands of depositors who want to save money at the same time, it will be overwhelmed. Moreover, this kind of sudden increase in customers is not a healthy and long-term business method for the bank. What the bank needs is a stable and long-term source of customers!

"The remaining people line up, go in one by one, and give the copper coins to the little servant who counts the money, and explain whether it is the survival period or regular. Remember to take your passbook and put your fingerprints on it~!"

Li Ke looked at

....................

"Shanchang, you are here, I just have something to ask you~!"

In the afternoon, Li Zexuan had just arrived at the workshop. Not long after, Li Tai took a mess of drawings and found Li Zexuan.

"Uh... Qingque, you haven't slept all night?"

Li Zexuan said in amazement.

Because Li Tai has messy hair and dark circles under his eyes at this time, this is very inconsistent with the character that Little Fatty has always liked to be clean. Obviously he did not sleep or did not sleep well last night!

Li Tai scratched his head, making his unkempt hair suddenly become more like a chicken coop, "Shanchang, I didn’t figure out something last night, so I read the book for a while, or I slept for a few hours. Shan Chang, you can help me solve a few problems, otherwise I will still have trouble sleeping tonight~!"

It's over!

Looking at the appearance of the little fat man, he is obviously obsessed! Just like the original Wang Ji!

"What's the problem? Tell me~!"

In order to let the little fat man sleep well, Li Zexuan took Li Tai to a meeting room and said.

Li Tai put down the drawing in his hand, looked at Li Zexuan, and said, "Shan Chang, I have understood the working principle and manufacturing process of the DC motor, battery, and diode, but I heard from Professor Mo yesterday, She mentioned that there is another electronic device that can amplify current. It seems to be called a triode. It is modified based on the principle of a diode. Can you tell me in detail?"

Li Zexuan was slightly surprised: "Qing Que, why do you suddenly want to hear this?"

Li Tai replied: "Shan Chang, I think we can do a lot of things by virtue of the characteristic that the transistor can amplify the current. For example, we can use it to increase the transmission power of the telegraph. In addition, I believe it can be used in many places. It is very important, so I think we should make it as soon as possible~!"

After hearing this, the surprise in Li Zexuan's eyes was fleeting, he tapped the table with his fingers lightly, and after a moment of indulgence, he spoke solemnly:

"Qingque, you are right, the transistor is indeed very important. The second killing project of uc Shumengyuan should be launched~!"

"The second killer project?"

Li Tai screamed, and suddenly said with a look of excitement: "Zhang Chang, is this second killer project related to the telegraph machine?"

Li Zexuan nodded and said: "Yes! But before I go into details, I have to confirm, Qingque, are you willing to participate in the second assassin project of the Academy!"

Li Tai replied without thinking, "Yes! Yes! Of course I do!"

Li Zexuan said gratified: "That's good! Today I will tell you briefly about this second killer project! The main purpose of this project is to improve the existing telegraph machine so that it can achieve ultra-long-distance wireless Communication, this ultra-long distance should mean at least a thousand miles!"

"A thousand miles?"

Li Tai opened his mouth wide in shock, and said in amazement: "Can't that cover the entire Datang?"

Li Zexuan nodded and said: "Yes! Although this sounds a bit exaggerated, it is not impossible from a technical perspective! With diodes and transistors, we can increase the transmission power of the telegraph on the one hand, and on the other On the one hand, a detector can be made to enhance the ability of telegraphs to recognize useful information in electromagnetic waves. In addition, we can also establish telegraph relay stations in major states and counties to relay electromagnetic waves. This three-pronged approach can achieve thousands of miles of communication. I decided that there was no difficulty~!"

Although Li Zexuan’s remarks have simplified a lot of descriptions as much as possible, they still contain a lot of professional terminology. What Li Tai listened to was half-knowing, "Shanchang, if the improved telegraph machine really You said that to realize the communication of thousands of miles, then in the future our Datang is very likely to be majestic!"

Li Zexuan smiled and said:

"It’s not very possible, it’s for sure! Datang will definitely become stronger and stronger in the world! In fact, this second killer project has another purpose, and that is to improve the telegraph machine this time. The academy should lay a certain foundation for the future electronic industry of Datang!

Like the previous electronic diodes, as well as the electronic triodes, resistors, capacitors, inductors, etc. to be built later, we have to find a way to produce some basic electronic components. Only in this way, we will be able to manufacture them later. A more advanced and convenient communication tool than the telegraph machine~! "

Li Tai was fascinated when he heard it. Hearing the words, he couldn't help but said with excitement: "Student Li Tai, I would like to help the mountain!"

Although he gave up his desire for reserve, he is still a Tang dynasty after all. He hopes that Datang will become stronger, especially after he learned Geography in the academy, he learned that the family is so big and there are so many In the country, his desire to make Datang invincible in the world is even stronger!

The pride and national honor of the Tang Dynasty is hard for others to understand.

Li Zexuan smiled, and said: "You are talented and you like to study. Of course, you are the second killer project! I just hope you don't cry out and get tired!!"

Li Tai shook his head and said: "The leader can rest assured that I have survived the military training. There is no such thing as Li Tai can't survive in this world! You can teach me how to make the transistor!"

How about military training is the best way to hone people? After experiencing military training, Fatty is full of courage to overcome all difficulties, because he already feels that there is nothing in this world that is more difficult than military training. !

Li Zexuan nodded. He picked up the drawing that Li Tai had, and began to write and draw: "If you say that these transistors are based on diode transformation~IndoMTL.com~ there is nothing wrong, because compared to Diodes and triodes only have one more grid. The so-called grid is a mesh or spiral electrode composed of metal filaments, which controls the intensity of the electric field on the cathode surface to change the cathode emission or capture secondary emission electrons. You can make a green bird like this..."

After half a quarter of an hour, Li Tai finally understood the working principle and production method of the electronic transistor. After digesting for a while, the little fat man frowned and said:

"Mountain long, after the transistor is made, how can I make sure that it can actually amplify the current? Is it necessary to judge the current strength according to the brightness of the light by connecting a light bulb at the back?"

This question can be regarded as stopping Li Zexuan.

After a long silence, just when Li Tai was about to lose patience, Li Zexuan finally spoke. He looked at Li Tai with some sympathy and said:

"Of course you can't use this method. Firstly, it's not accurate, and secondly, it's too troublesome. So, I think it's time to start the third killer project of Yanhuang Academy!"

Hearing that, Li Tai almost got off the chair by somersault, and slowly, he was a little surprised: "The third killer project? Shan Chang, is this a bit too fast?"

The second one has not started yet!

Li Zexuan shook his head and said: "It is indeed a bit too fast, but this is also a helpless move. The technology of the academy is developing too fast, and many basic equipment can't keep up, so multiple killer projects can only be carried out together!"

Li Tai thought for a while, and felt that what Li Zexuan said was reasonable, he sighed helplessly, and said, "Shanchang, what is the third killer project?"

Li Zexuan slowly said: "Ammeters, voltmeters, and some other basic instruments! The academy should take this opportunity to establish its own standards committee!"
