Under the guidance of Liu Zheng, Liangzhou Laboratory combined a steam engine with a hand-cranked generator.
Finally the design drawing was produced.
They looked at the design drawings in their hands with smiles on their faces.
With this blueprint, a factory that can generate electricity can be built.
However, in order to ensure that this invention can be successful, these technology geeks in Liangzhou Laboratory used a small steam engine to carry out this modification, so that he could provide the necessary power for the hand-cranked generator.
The result is that they succeeded.
But it was only half successful. They did combine a steam engine with a generator, used the steam engine to drive the gears, and then used the hand-operated generator to generate electricity.
But no matter how fast the steam engine turned the rocker, they still didn't get much power.
It can even be said to be rare.
Regarding this technical difficulty, they don't know the reason.
They could only invite Liu Zheng to answer them. Liu Zheng thought for a while, and finally remembered the knowledge taught by his teacher in junior high school among his vast knowledge.
The greater the magnetic force, the more electrical energy is generated.
"Change some magnets with stronger magnets and give them a try."
Everyone was stunned and didn't know why, but they still installed the magnet with stronger magnetic force on it as Liu Zheng said.
This time, the steam engine turned the hand-cranked engine and produced more powerful electricity.
But this raises a new problem, that is, although the power generated by this generator has become stronger.
But it is not stable and changes with frequency.
Seeing this situation, everyone became even more confused.
They all looked at Liu Zheng, and Liu Zheng didn't understand why such a situation occurred. Finally, after thinking for a long time, he slowly said: "These will be the two directions of our future research."
"One is to increase the voltage of the alternating current we currently produce, but we also need a transformer to control the voltage so that we can get and use the electricity."
"The other is direct current. Improving this generator allows it to continuously cut the magnetic wire and obtain a continuous and stable current."
Everyone was confused after hearing this.
Only they knew how to make a generator. As for the alternating current and direct current that Liu Zheng mentioned, they knew nothing about it. They also couldn't understand the voltage and current.
Someone raised their hands and asked: "Master Liu Zheng, we don't quite understand what you said. What do you mean?"
"Yes, yes, Master Liu Zheng, regarding AC and DC, they should both be electricity. What's the difference?"
Liu Zheng was stunned for a moment, looking at these top contemporary scientists who looked confused but eager for knowledge. He almost forgot that no one in this world has yet proposed the electromagnetic theory.
There has been almost no progress in the development of physics and electricity.
It was all driven by him.
Liu Zheng thought about the knowledge he had learned in his previous life and said: "The so-called direct current and alternating current, you can think of them as a straight iron rod that will never bend."
"Alternating current is a curve that can be transformed, but this curve changes regularly."
Liu Zheng squatted on the ground and drew two different lines, one straight and one winding.
