What will be the output voltage when Vx =0v?
(Where Vx > inverting input terminal of differential amplifier with one op-amp)

A. V<sub>o</sub> = -(1+R <sub>F</sub>/R<sub>1</sub>)*V<sub>1</sub>
B. V<sub>o</sub> = -(1- R <sub>F</sub>/ R<sub>1</sub>)*V<sub>1</sub>
C. V<sub>o</sub> = (1+ R <sub>F</sub>/ R<sub>1</sub>)*V<sub>1</sub>
D. V<sub>o</sub> = (R <sub>F</sub>/ R<sub>1</sub>)*V<sub>1</sub>
Answer» D. V<sub>o</sub> = (R <sub>F</sub>/ R<sub>1</sub>)*V<sub>1</sub>
