A sea of stars for top students

First of all, the diode has the function of one-way conduction and can prevent the flow of reverse current. After speaking, Wu Bin pointed to the next one, The electrolytic capacitor has the function of isolating DC flow and accumulating electric energy. It can be used for charging and discharging.

Finally, there is the resistor, because it has the function of blocking the flow of current, so when combined with the electrolytic capacitor, it can change the charging and discharging time of the circuit.

Crack, snap, snap.

After Wu Bin finished answering, Wei Tianshuo applauded firmly.

It seems that you have a very good and well-organized idea for solving the experimental questions, but now you are embarrassing the teacher.

Ah? Wu Bin looked at the teacher with a puzzled expression.

Actually, this was a question I asked myself last year. The first question stumped many outstanding students, so I later chose it as a meeting gift for all the freshmen.

After speaking, Wei Tianshuo picked up the chalk and wrote three words on the blackboard.

[Cue card]

The purpose is to explain the difference between the finals and the semi-finals, because the experimental questions have their own hierarchy. If you can't answer the first question, you won't be able to do it later, so you will have one chance to apply for cue cards.

Are you so conscientious? Wu Bin couldn't help sighing when he heard that there was such a preferential policy.

Of course you can't be so conscientious. As long as you apply for the reminder card, the 5 points for the first question will be lost, and you will be deducted 5 points. Of course, the premise of deducting these 5 points is that you will The whole question has been solved. If you haven’t solved it, you won’t get a single point.”

Oh~ Wu Bin nodded clearly.

At this point, Wu Bin finally understood that he did not play according to the teacher's routine and solved the first question directly, which made it impossible for the teacher to smoothly say No idea, right? In the finals , you will have a new choice when you run out of ideas. and the like.

But this can only be said that this teacher is very good at picking people. Wu Bin doesn't know whether others can do this experimental question, but now for Wu Bin, the electrical experimental questions are really the area where he is most confident. .

After the award presentation, Wu Bin returned to school and naturally could not give reports and give acceptance speeches all day long. He would definitely still be studying most of the time.

During the process, Wu Bin found that he seemed to be really talented in experimental questions. Whether it was the [real questions] from previous years that Bi Wanqing found, or the High School Physics Competition Practical Drill, the New Physics Experiment was marked as three Wu Bin accepted experimental questions of varying degrees of difficulty very quickly.

Especially for electricity, it may be due to the talent [Controlling Thunder and Lightning], which makes it even more powerful.

Okay, that's the end of the joke. I'm very happy to see that a student can answer the first question so easily. Next time I go to the laboratory, you will still answer the second question. Okay, go back and sit down.

Nodding, Wu Bin returned to his seat. Before he could even look up at the blackboard, all kinds of small praises came from all directions.

Wu Shen is awesome!

As expected of the sweeping monk.

Looking forward to Wu Shen's next performance.

…

After everyone clasped their fists in return, Wu Bin felt a little proud. It seemed that he was still very good at experimental questions, even in this class of all elites.

In the next hour or so, Wei Tianshuo told Wu Bin and others a lot of competition experience, supplemented by various questions. It can be said that the purpose of the lecture was very clear and clear, and there was no feeling that it was confusing.

Okay, let's take a twenty-minute break and we'll continue talking about light later.

Wei Tianshuo said while wiping the blackboard.

Huh~

Hearing the word rest, all the students stretched out and moved their necks and wrists.

After stretching, Li Yan originally planned to give Wu Bin a kiss, but when he looked over at his position, he found that he was no longer there.

Teacher Wei. At this time, Wu Bin ran up to the podium with a piece of scratch paper.

What's wrong? Wei Tianshuo asked while wiping the blackboard.

Wu Bin raised the scratch paper and said, You just said that the question is about how many times the light intensity can be increased near the bright spot in the center. Why don't you calculate the exact value?

Oh, here, because the estimated quantity value is enough, because you see, here the light comes over and converges to...

Looking at Wu Bin who was asking questions on the podium, Li Yan shrugged and couldn't help but complain: Doesn't this person know what the word rest means?

Finally, it was not until the 20-minute break was over that Wu Bin nodded gratefully to Wei Tianshuo and sat back down.

‘This guy is really interesting. ’

Wei Tianshuo took a sip of tea to moisten his throat, picked up the chalk and continued his lecture.

It wasn't until six o'clock in the evening. When Wei Tianshuo saw that it was almost time for dinner, he wiped off the content on the blackboard and said, Have you brought all the books I told you to bring?

Bring it. The students below responded in unison.

Well, I'll bring you Gaomiao tomorrow and I'll tell you a few selected competitive experimental questions. Okay, let's go eat. Do you remember where the canteen is?

Remember. All the students nodded.

Well, then go back to the dormitory to rest after eating. Come back to the classroom at 9 o'clock tomorrow morning.

goodbye teacher.

After waving to the teacher, several students left the classroom.

Well, bye. Wei Tianshuo waved to his classmates, then subconsciously glanced behind him, and was surprised to find that Wu Bin didn't come over this time, but when he looked up again, he found that he was still sitting in his seat.

Wu Bin, aren't you going to eat? Wei Tianshuo asked.

I'll go as soon as I finish this question. Wu Bin raised his head and replied.

At this time, Li Yan couldn't help but complained: Wu Shen, do you know what the combination of work and rest is?

I'm just enjoying myself, doing the questions is so interesting, Wu Bin replied.

I... Li Yan choked for a long time, and finally said Wu Shen is awesome! and then went to eat.

Wei Tianshuo smiled after hearing Wu Bin's words. He had always felt that Wu Bin was special since he started teaching these children, and his performance was indeed as he expected, and it was indeed very interesting.

As a senior teacher, he can easily tell the difference between pretending to work hard and really working hard.

Which question are you doing? Let me take a look. After wiping the blackboard, Wei Tianshuo walked down, put his hands behind his back and bent down to look at Wu Bin's notebook.

Just the wavelength question that the teacher wrote just now.

Didn't I tell you to go back to the dormitory and do it? Do you know what homework is?

Can't I wait? This question looks so interesting. Wu Bin said with a bright smile.

Hahaha, okay, okay. The teacher will work with you for a while.

No, teacher, if you are hungry, go and eat.

I'm not hungry. Just looking at you eating makes me feel full.

Wu Bin smiled awkwardly after understanding, while Wei Tianshuo laughed even louder.
