Title: I only knew that the mobile phone charger still has so many functions, and the master will never tell you

1. The Master's Secret
Today, I have the privilege of working as a plumber maintenance worker, and there are many anecdotes about it. However, the story I want to tell has nothing to do with water and electricity, but with mobile phone chargers that we commonly use in our daily lives.
Anyway, one day, I encountered a strange phenomenon in my repair work: the mobile phone charger can actually make a "buzzing" sound. I took a closer look curiously and found out that it was because there was a malfunction inside the charger. I thought this was the end of the story, but it turned out to be much more exciting than I had imagined.
I asked the master next to me about this phenomenon, hoping to get some explanation, but I was unexpectedly blocked by him.
"You don't understand this. He said as he turned to leave.
I was a little puzzled by the master's attitude, but I was even more determined to explore the question.
Second, the mystery of the charger
So, I started to dig deeper into mobile phone chargers. I found that the internal structure of a mobile phone charger is actually quite complex, not just a simple power converter, but also a powerful electronic device. In addition to charging the mobile phone, the charger also has a variety of protection functions such as over-voltage protection, over-current protection, short-circuit protection, etc., which can ensure the safety of mobile phone charging.
What surprised me even more is that the mobile phone charger can also be used to detect parameters such as current size and voltage stability, although these functions are not usually used, but they can come in handy in some special situations.
Through continuous experiments and research, I have a deeper understanding of how mobile phone chargers work, which also gives me some new understanding of the master's original answer. Perhaps, he didn't want me to explore this question because he felt that it was too early for me, not yet the time.
3. Practice and experience
After a period of study and practice, I finally mastered some tips for repairing mobile phone chargers. Once, my friend had a problem with the charger not working, so I picked up the toolbox and took my newfound knowledge to help him solve the problem.
When I opened the charger case, I found a capacitor that was causing the fault, and by replacing this capacitor, I successfully repaired the charger and got it back to working properly. When my friend saw my craftsmanship, he couldn't help but admire it, and said with emotion: "It turns out that the mobile phone charger still has so many functions, and the master will never tell you." ”
4. Summary and reflection
Through this experience, I deeply realized a truth: as a maintenance worker, we should not only be limited to superficial repair work, but also have an in-depth understanding of the tools in our hands. Only in this way can we be comfortable in the face of various problems and not be helpless.
At the same time, I also realized an important problem: the reason why the master was reluctant to tell me these functions of the mobile phone charger may be because he felt that I did not have the ability to master these knowledge now, or he wanted me to explore and explore it by myself. In either case, I should be humble and cautious, constantly learning and improving my skills in order to better serve my clients.
Maintenance work is mundane, but it's fun and challenging. I believe that as long as we are willing to continue to work hard and learn, we will be able to become an excellent maintenance worker and make our own contribution to the society.
