Question

Quizplus · Accepted Answer

A virtual ground is a concept used in electronic circuit design, often in op-amp circuits, to simulate a ground potential that is not actually connected to the physical ground. It allows for a reference point at a certain voltage level that behaves like ground within the circuit but does not facilitate a current flow to the actual ground.
