  • You are one of the best teachers that I have come across Sir. Your clarity and delivery is phenomenal on every level. As an Electrician, I have learnt a lot more about electronic components and their calculation. I am not contented being an Electrician but an Instrument Technician as well. Many thanks to you Sir. You have helped me alone this journey. Keep up the good work you are doing. May God continue to bless you and keep you safe always.

    Please never stop making videos. Your videos have helped solo many people including me. They are to the point and perfect!

    Thank you so much. I’ve been looking for a video explaining how class A/B/AB audio amplifiers work and every video just tells you you have a transistor, you have a cap, you have some resistors and that’s it. I’ve been looking for someone to explain to me what happens to the electricity exactly from the input to the output. What every component does to it and I finally found you. Thank you sir.
  • @butchness6980
    it is actually crazy how well he can explain things compared to my EE professors.
  • @maleenh1738
    Greatest tutor ever ...Loved your work always...helped me a lot since AL to now on my Higher studies as well as..Thank you so much sir
  • @Kent-vq5qb
    Man, you are the best teacher in the world. Your Calculus and Physics videos saved my college life. I do not even go to lessons. Because you teach better than my prosfessors. Thank you very much sir.
  • You are legit the only reason i pass math and thanks to you i can help my friends.
  • @strotter5795
    I want to say "thank you" for this video. I've been trying to learn some of this stuff as a hobby, but I've gotten nowhere because most people posting content assume that anyone watching these vids must be in possession of a baseline knowledge of electronics that I don't have. I've found the search for said knowledge is curiously difficult. It's been frustrating. This video was knowledgeable and informative. So many 'aha!' moments.
  • you are a legend!!!! literally saved me from failing😭 your explanations are so clear and easy to understand💛 my professer just does not make sense at all and made everything sounds suPER complicated. THANK YOUUUUUU!!!
  • You are one of the best teacher. Thank you for educating lakhs like me. God bless you with more knowledge.

    Though I was a computer engineer major in college, and am currently studying for a ham radio exam, circuits are still a mystery to me. This has helped get a glimpse into all the very high level ham radio circuit theory where we are just essentially memorizing a little theory and a lot of answers to questions that will be asked verbatim on the exam (50 questions from a pool of 600). I still marvel at the fact that people have discovered putting capacitors at C1 and C2 will filter out DC signal, and that Re controls the E voltage... (and all else about circuits). Thanks for this work. Much appreciated
  • @gasperh.9800
    you taught me as much as my teacher in 4 months of online school
  • @flapajawea
    This guy does everything, thank you so much 🙏
  • @markseidel19
    A nice and simple short video explaining more than a lecture.......
  • @lavenderbex
    I’m watching is video not even knowing what any of this stuff is just bc I like the sound of your voice😁
  • @PunmasterSTP
    NPN? More like “On you I can depend!”, because these videos are amazing. Thanks so much for making and sharing them!
  • @tefomaleke2879
    Thank you so Much Sir......please never stop making videos. They're beneficial to Many of us
