It was good to have magic. Li Xian no longer needed help from others and easily made several simplified versions of the lamp. Of course, there were many problems with such simplified versions.
For example, not only is it ugly, but the air inside the bulb cannot be kept clean.
"Fortunately, if we use stainless steel as the filament, it can at least be used for a few hours, which is enough for experiments and so on. It's just to show the country bumpkins how rare it is. With the jade lamp, it will be difficult for electric lamps to have a market for the time being."
When Li Xian returned to the laboratory with a few electric lights, he was stunned. What do you think Li Xian saw? He saw two wires as thick as a man's arms! Yes, Li Xian was sure that they were wires, but they were not wrapped in the lowest quality linen, but the highest quality silk.
Two thick "wires" extend from a one-meter-sized "Four-Elephant Generator" and are buried in two large pits, one in the south and one in the north - or mines.
The wire is thicker than the "generator", which really opened Li Xian's eyes!
Even so, these "researchers" stayed far away from the wires and dared not get close to them.
I… give up! Li Xian only felt that the sky was full of crows flying around, covering the sky and the sun; when it comes to fear of lightning, cultivators are definitely the best. But you are so afraid of it, it's also weird.
"Come here, come here, come here, I will teach you some knowledge about electricity!"
Needless to say, Li Xian began to explain the relevant knowledge and common sense of electricity, such as electromagnetic induction, electromagnetic eddy current heating, voltage, safe voltage, current, resistance; and of course, electric lights.
But Li Xian also encountered a problem. What units should be used to express voltage, current and resistance? Obviously, this unit cannot be directly copied. The definitions of voltage and resistance are also different.
In the end, Xu Ren came up with a suggestion that was barely acceptable to everyone. Voltage is represented by "thunder"; resistance is represented by "flash", and current is of course represented by "electricity".
It is stipulated that the voltage of the first successful four-elephant generator is set to 100 voltages, the current when the energy output is equivalent to one horsepower is 100 currents, and the resistance is 100 resistances; the rest can be deduced in the same way. (These two paragraphs can be skipped)
With electricity, everyone immediately started to make a simple model of an electromagnetic eddy current heating furnace and experimented by heating a piece of iron through electromagnetic induction; the result stunned everyone.
"It's amazing! There was no spiritual energy fluctuation at all, but the iron block actually melted!"
"Is this the electromagnetic force? No wonder the master swore us to keep it secret."
"This electric light is also amazing. Electricity is truly amazing. Master, can electricity replace spiritual energy to cultivate? And if we use electricity to cultivate, do we not have to fear heavenly punishment?"
This is a good question! Li Xian also had to admire this man's associative ability. Everyone looked at Li Xian again, with expectation in their eyes: Yes, if you use "electricity" to practice directly, of course you don't have to worry about heavenly tribulations such as thunder punishment; and thunder punishment accounts for almost 70% of heavenly tribulations.
Li Xian smiled bitterly: "Don't look at me, I don't know either, but I am also looking forward to it; everyone can study it when they have time, but be careful not to encounter the 'heavenly tribulation' in advance."
