1. What is the relationship, if any, between the polarity of the output and input voltages in experimental op-amp? Refer to your data. 7.5 Procedure 1. Realize the circuit in Figure 7.3. (R₁₁ =6,8k, R2=8,2k, R,=2k) 2. Dual power supply is +12 and -12. 3. 4. Use two different Rf and measure Vo values according to these resistors. Calculate Vo and fill Table 7.1 5. Compare experimental results with the theoretical values. Rs w + Table 7.1 Vn Vp R₁ w +Vcc Vo -Vcc v Figure 7.3 Measured R=6.8K V-9.81 Calculated V₁= R2=8.2K V=-10-30k Vo=
