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.)

What is the difference between a solar panel and a ground pump?
solar panels get energy from the sun and ground pumps get energy from turning water.
What is the electrical discharge between a cloud and the ground?
The electrical discharge between a cloud and the ground is known as lightning. It occurs when there is a difference in electrical charge between the cloud and the ground, and is typically accompanied by a bright flash and thunder. Lightning is a powerful natural phenomenon that can be dangerous and destructive.
Is there a difference between the Hubble space telescope and the Hubble telescope?
a major difference the huble space telescope is in orbit while the regular is in use only on the ground
What is the difference between an asteroid and a meteroid?
A metoriod is floating in space,a metor is falling trough our atmosphere, and a metorite is on the ground.
What is natural ground level?
what is the difference in between original ground level and natural ground level
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...
What is difference between an artersian well and an ordinary well?
An artesian well bubbles up out of the ground all by itself.
What is the principle of virtual ground?
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 the difference between the center tapped transformer and ordinary transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.

What is the difference between ground espresso and ground coffee?
The main difference between ground espresso and ground coffee is the fineness of the grind. Ground espresso is much finer than regular ground coffee, which results in a stronger and more concentrated flavor when brewed.
What is the difference between Stolon and Rhizoid?
rhizoids are below-ground, stolons are above-ground
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.
