Empress Industrial Project

Chapter 198 Electric Lamp ([-])

Xiao Yan was stunned when he heard it, and Han Qing was also surprised.

Xiao Yan swallowed, and asked: "What is this tungsten wire?"

this person...

Do you want to break the casserole and ask the end?
However, Qiao Yurong raised his eyebrows: "Tungsten is a metal element, more precisely a rare metal, and metal colors and properties are divided into two categories, ferrous metals and non-ferrous metals. Ferrous metals mainly refer to iron, manganese, Chromium and its alloys, such as steel, pig iron, iron alloy, cast iron, etc., metals other than ferrous metals are called non-ferrous metals, while tungsten belongs to the category of non-ferrous metals, and tungsten is the main metal material for making white weaving lamps."

After a pause, Qiao Yurong mocked, "Did you understand?"

She didn't believe that Xiao Yan, an ancient expert, could understand such a lot of industrial and professional things, so she just wanted to talk about these professional things, so as to save Xiao Yan from getting to the bottom of it.

Xiao Yan looked at Qiao Yurong with a clouded look, and asked, "My lord, what do you mean, gold, silver, iron, copper...are these all materials that can be used?"

……

Qiao Yurong suddenly felt that Xiao Yan might not understand what she said, but he could quickly understand the general meaning of what she said.

"That's what it means. Silver can be used to conduct electricity, but silver is too expensive, and it's basically copper wire." Zhu Yurong said depressingly.

"What is electricity?" Xiao Yan looked at Zhu Yurong with studious eyes.

……

Qiao Yurong suddenly felt a headache, and thought for a while: "If you continue to ask this question, what year and month will it take for this king to make a good thing, and when this king is finished, you will slowly study and think about it in this room, and you will be able to figure it out. You will understand what conduction is."

Xiao Yan knew that he was asking Qiao Yurong for trouble, so he didn't want to answer, but he was not reconciled, and continued to ask: "Is your conductive wire will light up when it is connected, is it the so-called conductive?"

Qiao Yurong ignored him.

"Is it this line?"

"Why do you connect different wires on the front and back?"

"Can it conduct electricity when connected in this way? Can it shine?"

……

Qiao Yu couldn't bear it anymore, her skin turned pink because of her anger, "You're never finished, do you want to see this king make something?"

With that said, Qiao Yurong looked at Han Qing: "Can you make your people shut up?"

When did Xiao Yan become his person?
Han Qing rolled his eyes unnaturally, and said to Xiao Yan: "Wouldn't it be better if you wait for the prince to make it and watch the experiment?"

Brothers all opened their mouths, Xiao Yan was curious in his heart, he could only bear back the impulsive thoughts in his heart, and quietly watched Zhu Yurong swing the things in her hands.

Qiao Yurong has actually reached the last step.

Yesterday, the copper wire of the wire was too thick, and the current was too high, causing it to catch fire, so today she used a thinner copper wire connected to a tungsten wire to conduct electricity.

Everything is ready.

Qiao Yurong connected the copper wire to the iron sheet of the magnet, and then pressed it with a cowhide to isolate the current, so as not to get an electric shock and electric shock to his hands.

I saw the wooden board in Qiao Yurong's hand, on the curved tungsten wire, a ray of light began to shine as quickly as lightning.

In the daytime, the light that shines in the pupils does not float, but shines blindingly, shining brightly in the room.

It may be daytime, the light is a bit dim, but even so, the light from the tungsten wire is still a bit dazzling.

The tungsten filament was just like that, shining proudly in Qiao Yurong's hands.

Xiao Yan and Han Qing's eyes were shocked, and they couldn't believe what they saw.

Han Qing's deep eyes brightened: "Xiao Yan, close all the windows and draw the curtains."

　Three shifts!
　　Thank you Xiyan for rewarding 498 book coins, and I am always grateful for your support!Refill!

　　I’m a little bit afraid that this article will take all men and women. Let me explain. Our protagonist is the empress in the end. Before that, the identity must have been concealed. It’s just a prince. Isn’t it common for a prince to be liked by many women?
　　Of course, our protagonist definitely likes men. As for women, except for Lan Chu, the others are just embellishments, making this article more colorful.
