Explain the concept of virtual ground in operational amplifiers?

Concept of virtual ground : This means that the differential input voltage $v_{1d}$ between the non inverting and inverting input terminals is essentially zero.
This is obvious because even if output voltage is few volts, due to large open loop gain of op-amp, the difference voltage $v_{id}$ at the input …
