Chapter 280 Test
After Qin An heard the explosion, he immediately got off his bicycle and squeezed through the crowd. When he saw the Black Dragon Guard in his hand, he immediately said: "Quick, wipe the wound with alcohol to avoid infection."
"Sir, don't be nervous, it's just a minor injury." Ying Zheng stepped forward and said.
"No matter how small a wound is, it can be infected, and in serious cases it can lead to the death of others." Qin An immediately retorted.
At this time, a doctor immediately took out alcohol and golden sore medicine to apply medicine to the injured Black Dragon Guards.
In fact, such a minor injury can be healed in a few days, so there is no need to be so nervous, but Qin An doesn't want to rush it.
Because this matter was private to him, he never thought that the experiment would be a success. He thought about countless possibilities of failure, but he did not expect that it would explode.
If you knew it would explode, you wouldn't have let everyone get so close.
Fortunately, it was only a minor injury and there were no major casualties. Otherwise, Qin An would have a troubled conscience for the rest of his life.
"Sir, why did it explode?" Meng Sheng asked.
Qin An shook his head and said, "This needs to be checked among the people, otherwise I wouldn't know."
"Sir, how do you need to check?" Meng Sheng asked again.
Qin An replied: "Collect the light bulbs and I will check them carefully. Is it a quality problem with the light bulbs, power issues with it, or something else? I will check it carefully.
At the same time, invent a new light bulb that will not explode even if there is a problem. Otherwise, who in the outside world would dare to use electric lights? Wouldn’t this be a source of discomfort for oneself? "
Ying Zheng walked up to Qin An and said, "Sir, what is going on?"
Qin An sighed and said: "The reason for the failed production should be the light bulb. I need to study the light bulb again."
Ying Zheng nodded and comforted: "Since it failed, let's continue research. We are not afraid of failure."
Although this failure disappointed Ying Zheng, seeing that the light bulb did turn on gave Ying Zheng hope again.
Therefore, when Ying Zheng saw that Qin An failed, and even almost endangered his life because the light bulb exploded, Ying Zheng was not angry.
Qin An smiled slightly and said: "Failure is the mother of success. It is because there are countless failures, and the reasons for failure are found from the failures, and finally success is achieved.
If I were so vulnerable, I wouldn't be able to become a PhD student, so the village chief doesn't have to worry about me. "
Ying Zheng breathed a sigh of relief. He was really afraid that Qin An would fail, which would ruin his plan to revitalize the Qin Dynasty.
"Sir, since you are not worried, I am relieved. If you need anything, just ask and the whole village will cooperate with you."
"These village chiefs, I want to study the reasons for the failure first. In the meantime, I hope I can be undisturbed by others for a few days."
"Okay, I'll arrange for Manman to deliver food to you. No one else is allowed to enter this courtyard unless you finish your research."
"Thank you, village chief."
…
Under the order of First Emperor Ying Zheng, the courtyard was cleared instantly, leaving Qin An standing alone in the courtyard looking at the broken light bulb.
There is also a team of black dragon guards outside the courtyard to prevent others from disturbing Qin An.
Qin An picked up the light bulb and looked left and right, but couldn't see anything interesting.
"Alas. Without a machine, I have no choice but to explode. The real reason is probably because the electricity is too strong." Qin An muttered to himself as he looked at the light bulb.
Immediately, Qin An took out another lantern, installed it, and started riding his bicycle again.
But this time the speed was not as fast as before, and the lights came on quickly.
Qin An looked at the brightness of the light bulb and began to slowly increase the speed, and the light bulb became brighter and brighter.
In the end, Qin An's speed became as fast as before, and the brightness of the light bulb was close to saturation, and it could no longer light up.
"boom."
Eventually, the second bulb went the way of the first and burst.
Because now there is no relationship, no one is hurt,
Qin An stopped riding, quickly got off the bicycle, came to the light bulb, smiled, and said: "Sure enough, the electricity was too strong, which caused the light bulb to be unable to withstand it, and finally burst.
It seems that you need to install a current limiter and a resistor to ensure that the light will not explode. "m.
Soon, Qin An shook his head again and said: "No, the light is very hot when it lights up. All light bulbs need to pass a high temperature test before they can be used. Otherwise, once the light bulb reaches the high temperature critical point, it will still explode."
In order to verify how long the light bulb can stay on, Qin An found ten Black Dragon Guards and took turns riding bicycles to generate electricity to prevent the light bulb from dimming.
Just like that, the third light bulb lit up all day and night.
The three women living in the yard saw that the light bulb was not broken and thought it was a success. They were all very happy and immediately informed Ying Zheng of the good news.
When Ying Zheng learned about this, he wanted to go and take a look, but was stopped by Li Si.
"Your Majesty, since you didn't say it was successful, it's still under testing. If you go now, you may disturb you, or an accident may happen.
Besides, the longer the test lasts, the higher the probability of success. You must not disturb him at this time. "
Ying Zheng nodded and said, "That makes sense. Let's wait. Manman, the three of you take good care of your husband. Don't make him too tired."
"Father, don't worry, sir, you can't see it." Ying Yinman said, "Not long after you went back, sir called ten Black Dragon Guards to help him ride.
Although the lights were on all night, my husband did not make any effort. It was all the work of the ten Black Dragon Guards. "
Li Yanran said: "Sir seems to be testing the speed. I saw that he kept asking the Black Dragon Guard not to be too fast or too slow.
Too fast and the lamp will be very bright and, like in the beginning, prone to breakage.
If the speed is too slow, the light will be dim and not bright enough.
Now that the gentleman has adjusted their speed, the brightness of the electric light is just right. I don’t know what you are still testing, sir? "
For her, it was now a success and she could use the light.
As they were talking, the bicycle generator died, and although it didn't explode, it shorted out and nearly caused a fire because of the hot wires.
In the yard, Qin An asked everyone to stay back and fetched water to put aside to avoid fire.
This is just in case. Qin An knows that it is impossible to cause a fire. This is just a bicycle generator, not a large generator. If it catches fire, you cannot put out the fire with water.
Qin An looked at the smoking bicycle generator and sighed: "Sure enough, if we use other materials to replace it, the quality cannot be guaranteed, and it was scrapped in just one day and one night. It is a pity."
"Sir, I'll inform the village chief." said a Black Dragon Guard.
Some people died, but not completely...
