D)virtual ground at the inverting

Question

Quizplus · Accepted Answer

The virtual ground at the inverting input of an operational amplifier (op-amp) is what makes the summing amplifier circuit possible. This virtual ground allows for multiple input signals to be effectively summed at the inverting input, with the op-amp maintaining the inverting input at the same potential as the non-inverting input (usually ground), thus enabling the summing operation.
