Concept of virtual ground in op amp

WebHari, You are right, the virtual ground is a concept, mental construct. The virtual ground only exists when the output is in the normal range, not at VOL and VOH level. Once the op amp output gets to maximum low or high level, the gain of the op amp drops to zero. The virtual ground only works if op amp gain is much greater than circuit ...
