For the circuit shown below, determine the Output voltage (Assume ?=5, differential input resistance=12 k?)

Question

Quizplus · Accepted Answer

The output voltage of an operational amplifier in a non-inverting configuration can be calculated using the formula Vout = Vin(1 + Rf/Rin), where Vin is the input voltage, Rf is the feedback resistance, and Rin is the input resistance. Given that β = 5 (which implies a feedback factor, suggesting that Rf/Rin = 5), and assuming the differential input resistance is 12kΩ does not directly affect the calculation since it's about the differential input, not the feedback or input resistance directly. If we assume a standard input voltage of 1V for simplicity (since the actual Vin is not provided), the output voltage Vout = 1V(1 + 5) = 6V. However, none of the provided options match this calculation, suggesting a misunderstanding in the question's given values or a missing piece of information (like the actual Vin value). Given the options and the information, without the specific input voltage, the exact calculation as per the formula cannot match the provided choices. Therefore, the correct answer based on standard operational amplifier calculations and the information provided cannot be accurately determined without assuming or knowing the input voltage. If we were to work backwards from the options provided and considering a feedback factor of 5, it suggests an amplification factor, but without the actual input voltage, pinpointing how the options were derived is speculative.
