Chapter 1481: Electric meter and triode! (Come on, college entrance examination students!)

"Don't crowd! Come one by one, line up, everyone will be able to line up

today~!"

Lantian County, Yanhuang Bank.

When the common people learned that they exchanged Tang Yuan at the Lantian

County bank without commission, and saved the money, they all flocked to the

house with most of the copper coins at home. At this time, the sun was rising

and the bank had just opened for business. It was already full of people, and

the little 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 they

are arguing because of queuing issues, it is easy to lose money. Considering

this situation, Li Ke hurriedly sent people to notify the officials of Lantian

County. 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 can't hold so many people!

The whole street in front of the Qianzhuang's gate is already full!

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

turn?"

"Yes! With so much money, it's impossible for the bank to collect all of it,

right?"

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

The young man was obviously trained before, and he said loudly after hearing

the words: "Guys don’t worry, 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 will be able to guarantee Safe deposit, everyone! If you have something

to do today and can’t wait, just go ahead and save when there are fewer people

behind. Our bank will accept it all! This, I promise you!"

The words of Xiao Si, let the people feel a little bit 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 in their homes this season.

But some big players in the team were still uneasy and questioned: "You

promise? You are a little boy, what kind of guarantee? If everyone listens to

you and goes back now, what if the bank does not accept it tomorrow? What to

compensate for our losses?"

As soon as the voice fell, there was a sparse echo from the crowd: "Yes! What

guarantee can you give as a young man? Who will pay for our losses?"

"Yes! Can't go back! Today, the old man must deposit all the copper coins in

Yanhuang Bank~!"

"Yes, yes! Don't leave!"

After such a fuss, the people who were preparing to go home before suddenly

stopped.

The little boy who was talking just now, seeing this scene, could not help but

flushed with anxiety, but in this case, even if he said more, it would not

help, because he was just a small boy in the money house!

"His guarantee is useless, what about mine?"

At this moment, a young man walked out of the lobby of the bank and said

blankly.

Although his voice was not loud, it happened to be able 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 fellow villagers recognize this king, then this king will explain

some things in front of you today!"

Li Ke looked at the crowd and said loudly: "No commissions, deposits for

interest, this is a preferential policy introduced by Yanhuang Bank of Lantian

County to all the people in our county. This policy is long-term and will

definitely not happen today. It will be gone tomorrow, I promise you in the

name of King Shu~!"

"His Royal Highness is wise~!"

"Your Highness is mighty~!"

After listening to Li Ke's vowed assurance, the people suddenly burst into

cheers.

After a while, the cheers faded away, and Li Ke went on to say: "In addition,

there is one thing that the king needs to explain to you in advance, that is,

the deposit interest rate of Yanhuang Bank is not permanent. This month is

1.75%. It may increase to 1.8 or 1.9%, but it may also decrease to 1.7%, and

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? The deposit interest rate might go up?"

"Good boy! Can any of you help with the calculations. If the interest rate is

1.9, how much interest can you earn for a year of deposit of 100 coins?"

"Master, a hundred guan deposits can earn one thousand and fifty liters a

year! Nearly two guanxi dollars!"

"Haha! Okay! Those five hundred cans are ten pens of interest! 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 to water Bai

Diezi today!"

"Yes, yes! Wait until some day is free before saving money!"

Hearing what Li Ke said, the people who were at the bottom of the line,

whether they were big households or ordinary people, turned around and left

one by one. Those at the top of the line did not leave much, because despite

the future deposit rates It may rise, but it may also fall! 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 scale of

Yanhuang Bank. It is true that the flow of people just now was too large and

scary, even if the scale of the bank was expanded. Ten times, it will be

overwhelming!

This is the same as modern banks. If any bank branch welcomes thousands of

depositors at the same time, it will be overwhelmed. Moreover, this sudden

surge of 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 hand over the copper

coins to the small 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 watched

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

"Shanchang, you are here, and 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's hair is messy and his eye circles are dark at this time, this

is very inconsistent with the character that the little fat man 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, "Shan Chang, I didn't figure out something last night, so I read

the book for a while and still slept a little. It's an hour. Shan Chang, you

can help me solve a few problems, or I will still have trouble sleeping

tonight~!"

That's it!

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

conference 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

this DC motor, battery, and diode, but I heard from Professor Mo yesterday

that you mentioned it to her earlier. However, 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 more about it?"

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. Besides, I

believe It can be used in many places, it is very important, so I think we

should make it as soon as possible~!"

Hearing this, the astonishment in Li Zexuan's eyes was fleeting, he tapped the

table lightly with his fingers, and after a moment of indulgence, he spoke

solemnly:

"Qingque, you are right. The transistor is indeed very important. It's time

for the second killing project of uc Shumeng Academy to start~!"

"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 Academy's second

killer project!"

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. Super long distance should mean at least a thousand miles!"

"A thousand miles?"

Li Tai opened his mouth wide in shock, and said in amazement, "Couldn't it

cover the entire Tang Dynasty?"

Li Zexuan nodded and said: "Yes! Although this sounds a bit exaggerated, it is

not impossible from a technical point of view! With diodes and transistors, we

can increase the transmission power of telegraphs on the one hand, and

manufacture on the other. Detectors are used 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 for electromagnetic wave reception and transmission relays. In this

three-pronged approach, it is absolutely impossible to achieve thousands of

miles of communication. Any difficulties~!"

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-knowledge, "Shanchang, if the improved telegraph machine

really does what you said , To achieve thousands of miles of communication,

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 and invincible in the world! In fact, this second killer project

has another purpose, and that is to improve the telegraph machine this time.

Datang's future electronics industry will lay a certain foundation!

Like the electronic diodes before, 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 make more telegraphs later. A more advanced and convenient

communication tool~! "

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, after he learned that the family is so big and there

are so many countries, His desire to make Datang invincible in the world is

even stronger!

The pride and national honor of the Tang people are hard for others to

understand.

Li Zexuan smiled and said, "You are talented and smart, and you like to study.

Of course, you can't do without you for this second killer project! I just

hope that you won't be tired out by the time you come!!"

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 quickly teach me how to make the transistor!"

How about military training is the best way to temper people. After

experiencing military training, Fatty is full of courage to overcome all

difficulties, because he already feels that nothing in this world is more

difficult than military training!

Li Zexuan nodded. He picked up Li Tai’s drawing and began to write and draw.

“If you say that these transistors are based on diode

transformation~www.mtlnovel.com~ there is nothing wrong, because compared to

diodes. The triode just has a grid. The so-called grid is a mesh or spiral

electrode composed of metal filaments, which controls the electric field

intensity on the cathode surface to change the cathode emission electrons or

capture the secondary emission electrons. You can make it like this..."

Half a quarter of an hour later, Li Tai finally understood the working

principle and production method of the electronic triode. After digesting for

a while, the little fat man frowned and said:

"Shanchang, after the transistor is made, how can I make sure that it can

actually amplify the current? Is it necessary to judge the strength of the

current by connecting an electric light to the back and the brightness of the

electric light?"

This question can be regarded as stopping Li Zexuan.

After a long silence, 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. It's not accurate, and it's too

troublesome. So, I think it's time to start the third killer project of

Yanhuang Academy!"

Hearing this, Li Tai almost got off the chair by somersault, and slowly, he

was a little surprised: "The third killer project? Shan Chang, isn't 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 academy's technology 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 other basic instruments! The

Academy should take this opportunity to establish its own standards

committee!"
