About Virtual ground
In OPAMP with negative feedback, the inverting terminal comes to the same voltage as the non-inverting terminal. If the non-inverting terminal is grounded the inverting terminal voltage also comes to 0. If the non-inverting terminal is at some other level, inverting terminal coes to that level.
Then in stead of calling it "virtual short" why is it called "virtual ground".
I am not really looking for a bookish answer to the term "virtual" here. I am confused about the term ground.
