I learnt how to derive all this from scratch two years ago, but only NOW does it make practical sense!!!

The world is analogic, the knowledge of the op qmp is essential for a electronic designer, good job Pete

Yes you are correct. Inverting op amp=> A=-R2/R1 Non-Inverting op amp=> A= 1+(R2/R1)

holy cow...i learnt so much in this 20 mins than i learnt in the whole module of linear circuits...it's so boring learning in a classroom...i hope i had a teacher like you...you rock man...thanks for your time and effort :)

I learned more about op-amps in these 20 minutes than from months of EE classes. That's what happens when the teacher actually enjoys what's being taught. Great job Pete.

Speaking of transistors, I never understood how the gates are controlled. Like, who and how are controlloing those millions of gates to turn on/off the source and drain?

A loads current requirements has to be meet. I don't know if I understand your question completely, but I might be able to help you. As your question stands, the answer is to check the datasheet of the component, that is connected to the opamp output, and look for I sub c equals value.

(I would presume the resistance of the op amp input is smaller than that of the cap, but I want to make sure.)

because an op amp is multi staged, so you get voltage and current through a bunch stages

Awesome video! My question is in a typical op amp circuit (using your model at 13:27 as an example), how do you ensure electricity doesn't go through the path of R1 -> C1 -> Op Amp Output? Or is that part of the design?

Could Anyone shed some light on how to do that calculation he put on the board c1=2pifc I can't figure out how to do that properly. thx, ( yes I'm a noob)

With the feedback loop configuration, how does one find out how much current shall be drawn by the load at the output of the opamp?

Check out your comments at time 10:40 in the video. I think you did not follow through when you mentioned the audio signal is low at the inverting input. You did not mention anywhere in the video how the calculated gain of 10 is amplified at the output of the op amp. So are you saying you will not get a signal when looking with an oscilloscope between inverting and non inverting inputs or are you saying you will not get a signal when looking at your inverting input in reference to ground?

i don't like the way you teach. you start off by drawing a circuit, then say what will happen (huge gain), but never put values in, or show a typical output. you seem to think you saying something makes it so. how about a little corroboration ? when i ran your first circuit in TINA, i did not get a HUGE gain. but then i had to guess at values because you didn't supply them.

I think the presentation is OK, but is not prepared, it's like he is figuring out what to say in the middle of the presentation. In general I like a more structured lesson, with more order, etc. but also, this is free so can't complain too much :)
