A node in a circuit that can be assumed to be (virtually) at earth potential. The term is often used to describe the inverting input of an operational amplifier connected in the inverting amplifier configuration (see diagram). The output voltage of the amplifier is given by
If A is large then v2 – v1 ≈ 0, i.e. virtually zero.
