Hi, I have a confusion regarding the concept of Virtual Ground. Aren't these two contradictory statements about this fundamental concepts.
1. Op amp has infinite input resistance (means inverting and non inverting terminals are open circuited)
2. There is zero potential drop across inverting and non-inverting terminal (the two terminals are short-circuited)
Please some senior member may reply. I do not want to get confused by some in-experienced postings.
I hope thats understandable for everyone.
Many Thanks,
Saad
