When the voltage at the op amp's inverting input is at the same potential as ground, but it can sink no current, this point is considered

Question

Quizplus · Accepted Answer

This point is considered a virtual ground because it is at the same potential as the ground without being physically connected to it, and it can't sink current, which is a characteristic behavior of the inverting input of an operational amplifier when it's properly configured in certain circuits.
