Determine the expression of output voltage for inverting summing amplifier consisting of four internal resistors? (Assume the value of internal resistors to be equal)

A. V<sub>o</sub> = -(R<sub>f</sub>/R )√ó(V<sub>a</sub> +V<sub>b</sub>+V<sub>c</sub>+V<sub>d</sub>)
B. V<sub>o</sub> = (R<sub>F</sub>/R)√ó(V<sub>a</sub> +V<sub>b</sub>+V<sub>c</sub>+V<sub>d</sub>)
C. V<sub>o</sub> = (R/ R<sub>F</sub>)√ó(V<sub>a</sub> +V<sub>b</sub>+V<sub>c</sub>+V<sub>d</sub>)
D. None of the mentioned
Answer» B. V<sub>o</sub> = (R<sub>F</sub>/R)‚Äö√†√∂‚àö‚â•(V<sub>a</sub> +V<sub>b</sub>+V<sub>c</sub>+V<sub>d</sub>)
