Why an Op amp Inverting Amplifier Appears to have no Input Signal

[@whitechannel2669]

I think that videos like this are a really precious resource: they go into the detail, in the direction of demystifying those aspects which are often neglected in traditional course, in favour of a more formal and mathematical approach. The math aspect is fundamental, of course, but explaining everything ONLY in terms of mathematical relations, without laying the fundations for an intuitive comprehension of the phonomena, risks to make things more difficult to understand. Thanks for posting!

Excellent explanations in a simple terms Sir...Wish we had tutorials these in our yesteryears!

[@SmilingAtom0-9]

Thank you sir.

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).

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

[@PanzerTanzer1]

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

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

[@ChrisHalden007]

That was quite a cool demonstration 👍

[@francismannion7075]

Fantastic! That explanation is clear and understandable, thank you.

Is "Dave" That he mentions Dave Jones in Australia? The EEV Blog guy?

[@unlokia]

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

im old school
i prefer transistors over op amps
