If no current flows between two points. ONE point is grounded then other point is said to be virtually grounded. THIS is called principle of virtual ground.

What is ordinary ground and virtual ground in difference?
Ordinary is when you can physically stand on this said ground. Virtual ground occurs when the ground is virtually the same between two disagreeing parties. EX: I like cake and you like cake. That is virtual ground in an argument. Whereas, a disagreement would be an atheist going to Church. However that's a paradox...
Should op amp remain in active region for virtual ground?
An op amp must remain in its active region for virtual ground to be preserved.
Which characteristics of Op-Amp is responsible for virtual ground?
The main parameter responsible for virtual ground of an Op-Amp is Input Impedance . Generally , for an Op-Amp it is very high . So , we can conclude that the characteristics of an Op-Amp responsible for virtual ground is high input impedance .
What is virtual ground and virtual short circuit?
VIRTUAL GROUND:-1]If the non-inverting (+) terminal of OP-AMP is connected to ground, then due to the "virtual short" existing between the two input terminals, the inverting (-) terminal also be at ground potential. hence it is said to be as "virtual ground".2]similarly if the inverting (-) terminal is connected to ground, then the non- inverting (+) terminal will be at "virtual ground" potential.3]The concept of virtual ground has been used extensively for amplifier analysis, specially we use this concept in the inverting amplifier.VIRTUAL SHORT:-1] The input impedance (Ri) of an OP-AMP is ideally infinite. Hence current "I" flowing from one input terminal to the other will be zero.2] Thus the voltage drop across Ri will be zero and both input terminals will be at the same potential. In other words they are virtually shorted to each other.
What is virtual ground in an op amp?
0 volt reference
What is Virtual ground?

When a hydrogen electron is in its ground state its principle quantum number is?

What principle governs the take off of a flight?
For an airplane taking off I believe that would be a combination of Bernoulli's principle and ground effect.
What is the difference between ordinary ground And virtual ground?
Ordinary ground is a simple connection to ground. Virtual ground is an op-amp's response to maintaining a reference point in the bridge with respect to an ordinary ground. This is why an op-amp makes a nearly ideal mixer - it allows you to sum multiple inputs together with little or (nearly) no cross-talk. (Limitations, of course, being based on CMRR and frequency response.)
How does camouflage break the figure ground principle?
By looking like a bloody bush of course.
What is difference between Real image and virtual image?
Real image-They are formed by actual intersection of light rays.It is inverted.It can be projected on a screen.It is formed on the mirror.Virtual image-It is formed when rays appear to meet at a point.It is laterally inverted and erect.It cannot be projected on a screen.It is formed behind the mirror.
