hi,
recently in uni i've been dealing alot with op-amps and most of the circuits i am required to build have virtual grounds. while knowing how to create a virtual ground, i do not really understand the concept of a virtual ground. all i know is that it is a point in the circuit where the voltage is held constant and is the substitute of a real ground. my lecturer's explanation is confusing and wikipedia's article is too deep. can u guys help out? i want to know how a virtual ground really works and when do we need one. thx in advance
