The principle of a transformer is actually quite simple.

Han Tianyun vaguely remembers that it seems to be the reverse application of the principle of electromagnetic induction.

It seems that two copper wire windings with different turns are used to pass the current from the side with fewer windings, and after passing through the secondary winding, the voltage can be increased by the output of electric energy.

He wasn't sure if that was the case.

However, I have always seen the appearance of a transformer in my previous life.

So he decided again to test the truth with practice.

He soon began experimenting in full swing.

And quickly forgot the time, and also forgot everything about the outside world.

But every road to success is covered with mud and cow dung, and people will hit the street again and again if they are not careful.

Fortunately, with the successful experience of making generators with bare hands in the past, Han Tianyun was very open to the current failure, and did not feel a little frustrated because of this.

On the contrary, after experiments again and again, I have strengthened my confidence and direction.

It has been proven that the ability of people to imitate can reach a point that surprises even oneself.

At the beginning, he just remembered the principle of electromagnetic induction, and Han Tianyun made a generator.

Now with Wu Yu's help, he has already collected a large number of copper wires, iron rods and other materials that may be used.

There is also a melting furnace, so the difficulty of making a transformer is actually much lower than that of a generator.

Moreover, he has a resistive body, which can be explored while energizing, and constantly improve the various problems encountered in the production process with his personal experience.

After more than ten days of tossing and sleeping in the cave, on this day, after connecting the generator current to the transformer again, he hurried to the other side and pinched the wire drawn from the transformer as usual.

"Ah......h

The next moment, Han Tianyun couldn't help but let out a wild scream.

I saw that he was covered in green smoke, his face was scorched, and his hair was on fire, and he looked so embarrassed and embarrassed.

But his face was full of excitement.

Through repeated exploration and practice, he finally succeeded.

The voltage of the electrical energy converted by the transformer should have exceeded several thousand volts, making his body feel numb and trembling for a while.

It wasn't even a matter of moments before his muscles began to ache and spasm.

Feeling bad, he hurriedly signaled Xiaohua to stop the generator and disconnect the power supply of the transformer.

"Haha...... The next moment, he couldn't help but jump and shout and run around the cave like a deer.

Xiaohua and the nurse watched him run wildly in the hole and screamed, but instead of being ridiculous, they were completely shocked.

In their eyes, Han Tianyun has incarnated into a master who can create thunder and lightning, and has incredible abilities.

In this world of revival, isn't a thunderbolt that can create a person directly into coke?

......

In the following days, Han Tianyun continued to experiment with transformers.

Of course, the content of the test has been to explore what level of output voltage can have an effect on one's quenching body, and then finally determine the rated output voltage of the transformer.

In the previous experiments, he had actually determined that the input voltage was about 220V alternating current.

Although he once emitted a voltage close to 1,000 volts by improving the generator, it not only had no effect on his quenching body, but also burned the coil of the transformer several times, making him finally give up the idea of increasing the voltage of the generator.

So, now he uses about 220V alternating current to convert thousands to 10,000 volts of alternating current to carry out his own quenching test.

This is another systematic project, because after sensing that the voltage is not suitable for him, he needs to re-add and reduce the number of turns of the copper wire to achieve the purpose of changing the transformer voltage.

And so another three days passed.

After numerous debuggings, the output voltage of the transformer was finally determined to be around 2KV.

Of course, this is an estimate based on the voltage he was convulsed from the first time he was electrified.

It is not known exactly how much voltage it is.

But this is obviously not very important, the important thing is that Han Tianyun has found the quenching voltage that suits the strength of his body.

This result made him ecstatic for a long time.

You must know that since coming to this world, he has been groping for a way to quench his body successfully, but he has no direction and good strategy.

It wasn't until I saw more people and more things in the outside world, and I had a clearer understanding of the setting of this world, that I had a further understanding and guess of my body.

And now, he has finally found the critical value of the voltage that his body can bear, and whether he can successfully quench his body depends on the specific practice in the future.

In the days that followed, the daily life of the cold sky clouds became extremely dull and boring.

He was immersed in the quenching body of high-voltage electricity almost all day long, stimulating his body with electric current over and over again, looking for the possibility of a breakthrough.

However, while Xiaohua used the generator current to quench her body, she often carried the nurse on her back, brought the golden snake and the queen bee, and drilled back to the ground under the demon tree from the hole dug to take a look at the scenery outside.

In this way, another half a month passed.

Han Tianyun could feel that his body was undergoing some subtle changes, but he still did not succeed in quenching his body and became a spiritual monk.

It made him feel a little manic.

I think that Xiaohua just came into contact with the generator, and directly broke through from Guwu to become a spiritual monk, how did he get here, and there was no movement in half a month?

He even began to wonder if his approach was wrong.

Could it be that voltage is not the key factor affecting the success of human quenching?

He frowned as he tried to find out what was wrong.

And at noon on this day, Xiaohua hurriedly carried the nurse back from the ground and came to the cold sky cloud who was quenched.

"The demon tree has sprouted!" she stared at Han Tianyun, her eyes were extremely excited.

"Oh?" Han Tianyun snapped back from his thoughts and opened his eyes in surprise.

"The electricity you send out is useful for it!" Xiaohua flashed her eyes wide, and her words were full of excitement.

"Let's go! Han Tianyun couldn't help but be eager in his heart, hurriedly turned off the generator, and drilled out of the ground with Xiaohua again.

Since he returned to the demon tree, he had to let the nurse and Xiaohua live in the underground cave because of food and water.

He never returned to the surface.

It's just that after the demon tree's fibrous roots found his generator again, he asked Xiaohua to charge the fibrous roots every day when she generated electricity.

Later, he brought back the generator for Wu Yu's quenching body, and improved the original generator, basically realizing uninterrupted power generation in turns 24 hours a day.

For convenience, he attached a wire directly to the fibrous roots to ensure that the roots could absorb electricity 24 hours a day.

And then I never bothered with it again.

In fact, more than half of the electricity emitted every day is sucked by the fibrous roots of the demon tree.

I didn't expect that today, it has finally budded again!!

After experiencing that war, and having the crescent moon in his chest, Han Tianyun's life can be said to have long been tied to this demon tree.

So when he saw the green sprouts dotted on the trunk of the stage-like demon tree, Han Tianyun felt the corners of his eyes moisten for no reason......
