Especially when he saw the half-drawn circuit diagram on the blackboard, Fang Hao couldn't stop laughing.

Four resistors, two in series, and finally in parallel, and then connect a power supply.

This Nima's junior high school physics question, no wonder the physics teacher advised Chu Nan, "You don't have to read that book."

Yes, the teacher is right, with Chu Nan's level, let's go back to junior high school and relearn junior high school physics.

Esoteric and complicated high school physics books, Chu Nan, that scumbag, really doesn't need to read anymore, he can't understand it!

The circuit diagram has not been drawn yet, and Fang Hao has already calculated the answer to the question on the blackboard through oral arithmetic.

Simple!

Not only did Fang Hao feel simple, but Liang Dazhuang and Xu Yang both felt simple.

Murong Xue and Wang Lele also looked at the problem that the physics teacher was solving, and they also felt that it was simple.

The rest of the students who raised their heads also felt that it was simple, isn't this a junior high school physics problem!

As long as he is a high school student, Chu Nan can't even do this, and he has to ask the teacher, waste!

What a waste!

Fang Hao shook his head with a smile, feeling that the physics teacher was really doing this too much, when was the time, and he still talked about this kind of simple scoring questions.

Even, Fang Hao laughed at himself, why was he still worried that Chu Nan would surpass him? At this level, he wouldn't be able to catch up with himself if he studied for another hundred years.

I wanted to continue to do the question, but Fang Hao was quite looking forward to seeing Chu Nan's embarrassment that he couldn't understand the question, so he put down his pen and continued to read patiently.

After only a while, Fang Hao's face became wrong, and he found that he couldn't understand the question.

The circuit diagram on the blackboard has changed, and the physics teacher has only connected another resistor between the two branches with resistors in series, a small change, and he can't even see it if he is not careful.

But with this small change, Fang Hao found that not only did he not know how to do this question, but he couldn't even read the question.

Fang Hao suddenly became anxious, he hurriedly copied the circuit diagram on the scratch paper, and then forced himself to calm down and began to solve the problem carefully.

However, the more this question is solved, the more deceived it becomes.

Wo Cao, what is the circuit diagram of this TM?

Series is not series, parallel connection is not parallel, what kind of connection is this?

Lying grass, how to solve this tm?

Lying on the grass, Fang Hao, who did not believe in evil, found the physics book again, found the explanation of the current part, read the book first, and then did the question.

......

Fang Hao, who watched back and forth several times, found that he still didn't know anything.

Lying grass, I'm afraid I've learned fake physics, right?

Fang Hao felt like he was about to collapse, could it be that my physics was so bad? I couldn't even solve a small junior high school physics problem?

Not only did Fang Hao collapse alone, in fact, all the students who tried to solve this circuit problem were all confused.

Why can't I even read the circuit diagram?

......

Time passed minute by minute, and before I knew it, the physics teacher had already changed the process of solving the question several times.

Finally, he nodded with satisfaction, and in this way, it should be correct.

Chu Nan also nodded, he had the same answer as the physics teacher, and the idea of some of the steps to solve the problem was roughly the same.

This also verifies his idea, he is indeed good at doing problems, and it is estimated that there is no need to learn anymore in this part of the circuit.

That's probably the power of the system!

The physics teacher looked at the blackboard, checked it one last time, and nodded, yes!

Wiping his sweat, he picked up the thermos cup and drank the wolfberry and jujube tea.

Cool, so cool, so cool!

It turns out that solving a puzzle is so wonderful.

The physics teacher seems to have returned to the era when he studied hard, and he also meditated hard to solve a difficult problem.

In the blink of an eye, decades have passed, and I have encountered problems again, but I still solved them.

The physics teacher sighed.

But the satisfaction of the harvest is also enormous.

The physics teacher turned around, and then remembered that there was a person standing next to him.

It's Chu Nan.

"Do you understand?"

"Understood!" Chu Nan nodded.

"Got it?"

"I really get it!"

Fang Hao doubted his life again.

To say that I can't do this question, I can barely forgive it.

However, the teacher wrote down all the steps to solve the problem, but he found that

I don't even understand the steps to solve the problem!

That's where the despair comes in.

He was going to do it again by himself through the teacher's problem-solving steps.

It turned out that I was thinking too much.

Did I really learn fake physics?

Fang Hao's whole face was confused.

As for Chu Nan saying that he understood, Fang Hao directly ignored this sentence.

TM, I don't even understand, can you Chu Nan do it?

on the podium.

The physics teacher is playful and ready to skin it.

He picked up the blackboard brush and erased all the steps to solve the problem.

"Come on, you count it again, I see if you understood just now!"

The physics teacher simply walked to the window and vacated the place for Chu Nan to solve the problem.

In fact, this is completely unnecessary, and high school students can't solve this problem.

He just wanted to disgust Chu Nan, who knew that this student had found an over-the-top question from that place to embarrass himself.

That's right, it's an over-the-top question.

But he can't do it if he doesn't do it.

Be a role model for teachers and answer questions for students, how can you say no?

As a man, how can you say no in front of students?

The physics teacher had forgotten what part of the knowledge was involved in this question, but he was sure that it was something that was only learned in college.

No way, although the physics teacher has been in the high school physics community for decades, he has also returned a lot of knowledge to the university teacher.

So it took him a lot of time to solve this not difficult college circuit analysis problem.

Chu Nan walked to the place where the physics teacher solved the problem just now and began to solve the problem.

The corners of the physics teacher's mouth set up a strange arc, did he really understand?

Got the fart!

Lao Tzu wasted a lot of effort to solve this problem, if it weren't for the solid physics in college, I remembered a few basic laws, I couldn't solve this problem, he is a high school student, can he do it?

Not to mention a high school student, even if you come in a group and call all the students in the school, you can't solve this problem.

A high school student should be able to solve this problem.

I ate all the coffin boards of my grandfather Newton.

"From the 1, 2, 3, 4, 5 can be obtained i1 = 2A, i2 = 0.5A, i3 = 4A, i5 = 1A. ”

At this time, Chu Nan has already solved the problem.

In fact, the amount of computation in this problem is not large, and oral arithmetic is fine, but it is rare how to use the basic theorem to analyze the circuit.

When the physics teacher saw Chu Nan's problem-solving steps, he finally remembered something.

Isn't this Kirchhoff's law!

Isn't this the mesh analysis method?

Isn't this the same law that caused me to fail in the first place!

The physics teacher remembered.

I see, it seems that this Chu Nan really understands this question.

The physics teacher smiled with relief.

What is commendable is that from Chu Nan's problem-solving process, he can see that Chu Nan not only solved the correct answer, but also solved the problem with a simpler idea than his own method.

Drawing inferences, this is the most valuable part for students.

Don't ask for inferences, physics teachers just want ordinary students to keep up with their own ideas and burn high incense!

But Chu Nan not only drew inferences, but what he reflected on was more clever and concise than what he gave examples.

It seems that this Chu Nan is not simple!

At least he's better than his old bones in circuit analysis!

The physics teacher was very relieved to see that the students he taught were better than him.

Suddenly, the physics teacher thought that it was also this Chu Nan a few days ago, writing math homework in his physics class.

At that time, I secretly blamed him.

It turns out that it's because I understand everything, so I write other homework.

That's right, people like Chu Nan who can understand college physics, and then look at high school physics, they will indeed feel simple and boring.

It turned out that he was wrong to blame him!

The more the physics teacher looks at Chu Nan, the more pleasing it is, just like a mother-in-law looking at her son-in-law, the more she looks at it, the more satisfied she becomes.

This young man, why is he so handsome!

And also a table of talents.

If it weren't for the fact that the granddaughter was still young, otherwise the two would have to meet for a meal.
