I have been informed in the class group before, today our electromagnetism course will be a little bit modified, everyone now directly follow me to the laboratory building, do an alternating current and rectifier filter circuit experiment, if the time is sufficient, you can also continue to enter an oscilloscope measurement time experiment. ”

"Some manuals and rules when doing experiments, the squad leader remembers to tell me more, after the end of the experimental class, all the instruments must be in place...."

"Considering everyone's teamwork ability, the group of our electromagnetism course is randomly assigned, if any student is not satisfied with the grouping, they can come to me alone."

The teacher of electromagnetism is named Tan Liangming, who often likes to wear a pair of brown and yellow pants, and is the youngest of several teachers in the physics class.

Nearly a month has passed in college life unconsciously, and everyone has slowly become familiar with this rhythm, today's class is an experimental class, but Su Mu was still slightly surprised when he heard Tan Liangming report the group list.

Because he was actually placed in the same group as Gu Tunan!!

The random assignment of this group was too coincidental, and when the other students heard that Su Mu and Gu Tunan, two male theologians, were in the same group, they couldn't help but let out some boos.

"This experiment was actually told to you before the Mid-Autumn Festival, so I default to your preview in advance, if there are any students who are not clear, you can also ask for help from other members of the group."

Under the leadership of Tan Liangming, the students slowly walked to the experimental building, which is a little old, but through the window, all kinds of instruments are very neat, and the entire corridor is also very clean, with a "scientific taste".

A total of 38 students in the class were divided into 12 groups, most of them were 3-person groups, and two were 4-person groups.

In Su Mu's group, in addition to Gu Tunan, there is also a girl named Lin Kui.

Lin Kui looks like a very homely girl, she doesn't dress up much, and her presence in the class is not high.

Su Mu only vaguely remembered that she said that she was a Tianjin girl when she introduced herself, and even he, the squad leader, didn't know much about other information.

When I arrived at the lab, the teacher once again told me some rules of the lab, and then simply assigned some tasks on the blackboard.

"Shall we appoint a team leader?" Gu Tunan opened his mouth and asked Su Mu: "When the time comes, it will be more convenient if you hand in some homework and communicate with the teacher." ”

"Team leader? It's all right. Su Mu nodded indifferently.

"Then if you don't mind, I'll be the team leader." Gu Tunan was still as confident as ever when he said this, his height was a little taller than Su Mu, and he always gave people a feeling of being lonely.

"Okay."

Su Mu nodded.

He had already read this experiment in books, and it was probably very simple, and it shouldn't be very difficult to actually operate.

Since Gu Tunan wanted to be the team leader to be in charge, Su Mu felt that he could save a lot of things.

Moreover, Su Mu actually began to admire Gu Tunan a little bit in his heart.

Although Gu Tunan speaks and does things very deliberately many times, this kind of character that can clearly indicate his purpose is really not learned by Su Mu himself.

"What about Lin Kui? What do you think? Gu Tunan smiled slightly at Lin Kui.

Lin Kui's body trembled slightly, and his current state was a little strange.

She is not short, but in front of Gu Tunan, she still wants a little chicken cub who has no power to restrain the chicken, and when Gu Tunan asks her opinion, she only dares to nod weakly.

She didn't know whether her luck was good or bad, she was able to stay in the same group as the two male gods in the class, and when she looked at Su Mu with her left eye and Gu Tunan with her right eye, Lin Kui suddenly thought of what she had been chasing all this time.

As a senior rotten girl, it was the first time she had seen such a confrontation between two school tyrants in real life.

So much so that the body is still very excited and has not reacted.

......

"Then let's just start the experiment, shall we?"

"I looked at the time, and if I had done it faster, it would have been enough for everyone to do it once." Gu Tunan opened his mouth and said, consciously assuming the position of team leader.

"Lin Kui help me get the instrument, Su Mu can be responsible for it first....??"

Gu Tunan was originally arranging the first division of the task, and wanted to let Su Mu be responsible for recording it during the first test, but when he saw Su Mu's experiment manual, he suddenly stopped.

"Why don't you use your own experiment manual, this should be handed in by then, right?"

Gu Tunan saw that a lot of things had been written in Su Mu's experiment manual, and subconsciously thought that this was someone else's textbook that Su Mu had borrowed.

"It's my own." Su Mu nodded and replied.

"Your own?"

Gu Tunan's eyes were a little strange, today is the first experimental course, if it is other theoretical knowledge, it is still easy to understand, but if it is an experimental class, can this thing still be mentioned and written?

Seeing Gu Tunan's doubts, Su Mu smiled and opened the book: "No, I left all the positions to fill in the data empty, but I just wrote down some theoretical knowledge." ”

"The main thing is that I don't usually have anything to do, so I pre-studied it in advance."

In addition to some data to fill in in the experiment manual, in fact, there are more things to pay attention to and error analysis, error analysis is just that, Su Mu has long been familiar with it.

"Okay."

Gu Tunan nodded.

Everyone learns differently.

However, Gu Tunan's eyes when he looked at Su Mu also had some strange feelings.

After all, Su Mu's "preview" is too much, and he has almost finished writing the precautions of the entire book, so much so that at the beginning, Gu Tunan thought it was an old book.

.......

The experiment was carried out step by step, and Lin Kui was debugging the data and checking it on the side.

"There seems to be a slight deviation between the RMS value of the AC voltage and the calculated value." She said in a whispered tone.

Su Mu nodded and explained seriously:

"Let's check for bad contact first."

"And the Vpp of the sinusoidal AC voltage waveform should be subject to the oscilloscope observation, no need to look at the voltage displayed by the LCD on the right side of the signal generator, the frequency of the signal generator output is different, and it is acceptable that the voltage display value has a certain error with the actual output peak value."
