On January 22, Xinyang, Henan, a high school took online classes at home due to the epidemic, and the physics teacher of the third year of high school actually dismantled his mobile phone appliances in order to let everyone learn better.
When talking about wireless charging, the teacher went to the mobile phone store in advance to take apart his Apple iPhone 11 mobile phone. The live broadcast said: The back cover of the mobile phone is wrapped around an inductive electromotive force, and through the rectifier circuit, the alternating current is turned into direct current...
When talking about the application of vortex, he also took apart the induction cooker at home live, and took physical objects and photos to explain in detail to everyone during the class.
Some students said: When I saw the teacher dismantle the iPhone 11, the entire live barrage exploded [bitter] [bitter], and the teacher asked us not to try it ourselves in private. But the teacher is really good, he did this, all to make us understand more clearly, thank you very much for the teacher's good intentions.
After the lecture, the teacher also intimately reminded the students not to dismantle it themselves, which is more dangerous.
The students said that the previous teacher's lecture was particularly boring, and felt that the teacher was very dedicated and the way of lecturing was also very interesting.
This lesson is about a bit of a costly thing...
This is too dedicated, and the teacher is very rare
The physiological hygiene teacher took a detour
Hahahaha teacher really put a bloody money for teaching
