Answer / Nikhil Singh Pundir

Ground in electronics refers to a common reference point that is connected to earth. It serves as a zero voltage level in electrical circuits. A Virtual Ground (VGND) is a simulated ground in a circuit, not physically connected to the actual ground. It is used when multiple grounds have different voltages but are still treated as having the same potential. This can be useful in certain applications such as op-amp circuits and mixed-signal designs.
