Table 1 Results for Experiment B1 R1, ΚΩ |ოო Vs (+ 397 3.3 Fig. 2 Circuit for Experiment B1 For all partners: R₁ = 3.3 k2, R2 = 3.9 k2, Rt3 = 4.7 k 1) Build your circuit according to Fig. 2. Supply power +/- 22 V to the op amp. Create a common ground for all related equipment (DC power supply, function generator, oscilloscope, and your circuit) by connecting the "COM" of the DC power supply to the common ground of your circuit. 3.9 4.7 Rf 2) Supply DC voltage Vs=2V to your circuit. To obtain DC supply using the function generator, press "Utility" and select DC ON. Measure the values of Vo and values of current I for the specified values of Rt. Record your results in Table 1. 3) Explain why the feedback current I in Table 1 does not change i.e. it remains almost constant. R₂=3.3 kQ Calculated gain G I + Measured Vo, V Vo Measured I, A
