Nice video... Thanks sir for sharing godbless

Thanks for the explanation! I always struggled with understanding (and visualizing) op-amps.

This is by far the best analogy... Thank You

For me, it helps to remember that the op amp has its own power source. It's not just a passive result of the inputs, it's actively using its power to compensate against changes to the input(s).

Hello Bob.
Is this the “corrected” version linked to on the version on Dave’s channel (which has now vanished)?

Op Amps make sense when Bob explains them. Thank you, Bob! 🙂 (oh, and thank you, Cindy 🙂)!
