The values for R 1 and R 2 is to be calculated for the circuit shown below. Concept introduction: From the given circuit, the relation between the input and output voltage is obtained using virtual short and potential divider concept. The output is observed to follow the input with a gain with the relation, v 0 = v i ( R 1 + R 2 R 1 ) Based on the input-output relation given v 0 = 8.5 v i and R 1 + R 2 = 50.0 k Ω , we can find the values for resistances.

Principles of Instrumental Analysis, Chapter 3, Problem 3.6QAP

Concept introduction:

From the given circuit, the relation between the input and output voltage is obtained using virtual short and potential divider concept. The output is observed to follow the input with a gain with the relation,

v0=vi(R1+R2R1)

Based on the input-output relation given v0=8.5vi and R1+R2=50.0 kΩ, we can find the values for resistances.
