      Like all your excellent videos. I have seen this explanation of virtual ground many times, but it is always lacking something. Here the opamp is drawn with a feedback loop, but the huge gain of the open loop opamp is used to explain that the inputs are at virtual ground. Then it turns out that the gain of the opamp with feedback is by several factors smaller than the open loop gain. This would then mean that the inputs are not at virtual ground? Am I missing something in this explanaton. I like to look at it as a differential amplifier with equal bias currents in each branch, so that both inputs have the same voltage.

Like watching youtube tutorials in the comfort of Your home Versus some huge lecture room with a lecture session that cant be paused or rewind.

      Yes, if you have seen my last videos on op-amp (Integrator and Differentiator), I have taken some examples. And anyway I am going to make a dedicated video on problems based on the op-amp. But before I make that video, I will cover few topics like the gain-bandwidth product, slew rate, CMRR and offset voltages in Op-amp. So, that I can cover a variety of questions based on the op-amp.

    Like all your videos. I have seen this explanation of virtual ground many times, but it is always lacking something. Here the opamp is drawn with a feedback loop, but the huge gain of the open loop opamp is used to explain that the inputs are at virtual ground. Then it turns out that the gain of the opamp with feedback is by several factors smaller than the open loop gain. This would then mean that the inputs are not at virtual ground? Probably a good explanation that would include a differential amplifier with matching, and equal branch currents is too advanced.

    I think being 180 degree out of phase and being negative is really different thing. The effect of 180 degree phase shift is the same as negative signal only for sinusidal and some symmetric signals. not all of them.
