This knowledge, which sounds profound and complex, will become the focus of their research in the future.
Just thinking about it is enough to excite them.
"Don't worry, sir, we will solve these problems as soon as possible. Based on what you said, how should we know the magnitude of the voltage or the magnitude of the current?"
Liu Zheng almost forgot that they were not scientists in the previous life who had explored and developed it bit by bit. They have not yet made an ammeter that can measure current.
Liu Zheng immediately wrote down the method of making an ammeter.
And tell them Ohm's law and electromagnetic law and let them study it themselves.
As for why Liu Zheng didn't explain it, it's because Liu Zheng didn't fully understand the complexity of these laws.
Let's leave things like this to these fanatical scientists.
Liu Zheng visited the electrical research laboratory, but he was thinking that hand-cranked generators had already been invented.
Should he let the light bulb appear in advance to facilitate the subsequent scientific research here?
Liu Zheng thought about it again and felt that it was still somewhat urgent, but he couldn't rush it.
Tungsten light bulbs are definitely useless now.
Their current process can't produce such a light bulb, so they can only consider lower-power alternatives.
Naturally, this matter was all left to those scientists.
Liu Zheng came to the research laboratory on engine development again, which will replace steam engines in the future.
It was also because of the invention of the engine that small but powerful battleships were able to flex their muscles on the battlefield.
It was also because of the emergence of the engine that cars replaced horse-drawn carriages and changed the way people travel.
It also changed the way of war, and the invention of the engine directly promoted the advent of tanks.
If we use the setting of the world of cultivating immortals to describe this era without nuclear weapons and powerful bombs, tanks are the land gods on the ground.
The armor of tanks and the firepower of artillery shells, the so-called cavalry, the so-called Cossack warriors, this cannon, that cannon.
Not enough to see at all.
Long Yan has mastered the steel materials that can be used to make tank armor.
Other technologies for building tanks are also available.
But they have never successfully developed the core engine.
If the engine can be developed, it will not only be a tank, but also an airplane, mankind's hope for heaven, a product of the combination of aerodynamics and engines.
In today's era of aerodynamics, due to the emergence of Liu Zheng, some people have begun to conduct extensive research on Liu Zheng's successful cases.
Liu Zheng once successfully built a glider and even used it to destroy a country's most important economic zone.
Liu Zheng also sent people to fly in the sky.
These are all manifestations of aerodynamic research results.
But now, engine research has reached a bottleneck.
The engine is an internal combustion engine. They don't know how to put coal in it and burn it, and then make the machine run.
They also tried a lot of combustion materials, some of which could burn, but there was no way to provide reliable stability.
Sometimes, one combustion and one movement can completely destroy the engine.
There are also times when burning is not possible.
But these researchers have not found a way to solve these problems.
Liu Zheng came today to solve their fuel problem.
Liu Zheng brought another burning substance to the engine laboratory, which was a small jar of oil found on an unnamed island.
Liu Zheng blended the oil with alcohol.
Put it inside the fuel tank.
I ordered the person to crank the engine. After a while, the engine made a beeping sound.
Eventually the sound got louder and louder, until finally they pulled out the stick and stopped spinning it.
Give it a try!
The engine buzzed, and everyone stared at the engine blankly.
He's up and running now.
After a brief silence, everyone burst into cheers like a mountain roar and a tsunami.
"It's done, it's done!"
"Our efforts are not in vain!"
"Master Liu Zheng, what exactly did you add to the fuel of the engine?"
"It's never turned like it does today!"
Liu Zheng looked at the rotating engine and laughed. He was about to speak, but the engine suddenly seemed to misfire, and there was no sound anymore.
As it approached, white smoke came out, and the engine stopped moving.
Everyone's happy mood was suddenly interrupted. Liu Zheng looked at everyone, laughed dryly and said: "No matter what, this is a good sign!"
"At least he's functioning now."
Everyone was stunned and thought for a moment, it was indeed true, this was a good sign!
Being able to run is better than anything else!
At least it can prove that their experimental direction is on the right track.
That alone is cause for celebration.
After thinking of this, everyone's frustration disappeared in an instant and turned into a more powerful motivation.
They looked at what Liu Zheng was holding and said, "Sir, what is that in your hand?"
"Why is it that after mixing it with alcohol, it can make the engine we have been unsuccessfully experimenting with run?"
Liu Zheng shook the small can of oil in his hand and said, "This will be our treasure from now on. Only with this thing can our engine run."
Everyone's eyes lit up. The person responsible for researching the engine stared at the small can of oil in Liu Zheng's hand and said, "Master Liu Zheng, do you think this is right?"
Liu Zheng had already guessed what he was going to say. He slapped the small can of oil on the table and said directly: "I'll leave this to you. You don't need to worry about oil in your laboratory from now on."
"I need you to research the engine as soon as possible."
"Now it seems that you are not far away from final success."
Everyone nodded excitedly: "Yes, we hope so!"
"Hopefully the engine will be developed soon."
Liu Zheng nodded and did not stay long, but left here as if running away.
Engine research and development is even more difficult. Now that the fuel problem has been solved, there are still problems with ignition, operation, cooling, and stability.
In the era before he time traveled, car engine technology was already very advanced, but engines were almost being replaced by electric motors, and there was still no engine that could guarantee good stability and not break down at all.
They are all in a state of having no major problems and constant minor problems.
This subject may not be as complicated as electricity, but it requires the cooperation of many disciplines.
After seeing these two future inventions, the generator and the engine, Liu Zheng came to another research department, which was different from other departments.
No one is allowed to enter, there will be consequences at your own risk
These eight characters are written in scarlet, as if to remind those who want to enter this department to be mentally prepared.
Researchers from other departments would be far away just passing by here.
Liu Zheng looked at the name written on the department, Department of Medicine.
He complained in his mind, should it be a medical department or a disease department...
Liu Zheng shook his head and opened the door.
