virtual ground

a type of ground that appears at the inverting input of an op amp that uses negative feedback. It`s called virtual ground because it has some of, but not all, the effects of a mechanical ground. Specifically, it is ground for voltage but not for current. A node that is a virtual ground has 0 V with respect to ground, but the node has no path for current to ground.
