D) Vout/Vin = Rout/Rin

Question

Quizplus · Accepted Answer

The voltage gain (Av) for an operational amplifier in an inverting configuration is given by the formula Vout/Vin = - Rf/Rin, where Rf is the feedback resistor and Rin is the input resistor. This formula represents the relationship between the output voltage (Vout), the input voltage (Vin), and the resistors in the circuit.
