    Dear professor. I appreciate you posting these. Out of the many videos I have watched on this topic, your patient presentation is among the best and easy to understand and absorb. Your presentation style, where you wait for the students to answer necessary fundamentals questions, is a good way of presenting.
    Many other videos and lectures on these topics JUST FLY past these fundamental questions. At which time someone like me GETS STUCK and then shuts down and loses confidence.
    As you were asking these questions and waiting for an answer, I was answering the questions out loud as if I were there.
    I will look to your videos for any topics I need a good lecture on.
    And at my university, my professor gave these same examples during lecture, and they FLEW RIGHT OVER MY HEAD! It is nice to have someone that "can speak my language."
    Thank you. And if you still record lectures in this format, please keep posting.

      Correction, it is indeed Electrical and not electronics. Electronics involves the components of intricate systems with in a device like for example an iPhone. Basic circuit / electrical theory like this is actually Electrical Engineering* I know this to be the case because the associate dean of my engineering department spent and hour telling us the difference between Electronics and Electrical ahahah.

    The reason for the voltage follower is to isolate the connection between the voltage source to the output load: the source voltage sees an infinite input impedance and the load sees zero output impedance which is ideal when connecting one circuit to the next......this is also the reason to call this circuit a "Buffer".

    Professor, your videos are amazing!
    However, because I want more students to come and watch your videos, I suggest that you give each example a TITLE. for example, before you do the inverting amp, title the example "inverting amplifier" because most students come to watch specific material and they might watch the example and not even know that it's what they need to know for class!
    thank you so much again for posting the videos!

    That voltage followed seems weird. Wouldn't a capacitor be a better power on/off transition element to smooth out the otherwise square pulse wave?

    for noninverting amp, i don know why the current I1 flows at the resister R linked ground . please explain the reason

    • @petergorelov418
      @petergorelov418 8 лет назад

      V-=V+, remember? And V-=V+=Vin. So, the left terminal of the resistor R connected to the ground and the right terminal of the resistor R connected to Vin. So, here is your current flowing.

  • @rinrin6454
    @rinrin6454 8 лет назад

    If an ideal op amp has infinite resistance there, but real life cannot mimic it, why don't they just make it an open circuit? Is it in actuality necessary for some current to flow there?
