Guest Video: Bob DuHamel - How Opamp Virtual Grounds Work

[Brumby]

I'm trying not to.

All this chest beating is taking the issue OTT, IMO.

Sure, there are arguments as to why this approach is better than that approach - but the point I took away from the video is that it shows a FUNDAMENTAL in understanding Op amp functionality.

Arguing which is better is, in my mind, exactly the same as saying Kirchhoff's voltage law is better than Kirchhoff's current law.  Come on .....



For the purpose of the video, I found the presentation very, very useful - and adding the comments I posted earlier, makes for a complete understanding of the fundamental concept from the voltage perspective.

........ IMHO
