b. You now add an Op Amp (powered by ±5V) to the voltage divider. For this circuit, provide a governing transfer function. If Vin=5V, calculate Vout at the following two conditions: 1) R=100Ω and RS=100Ω, and 2) R=100Ω and RS=105Ω. Calculate sensitivity in units of Volt/Ohm. Show all work. (5 points)

Answer:
1) Vout = -25 V
2) Vout = -25.61 V
The sensitivity is 0.122 V/Ω
Explanation:
The equation for Vout is:
1) Given:
Rf = 10 K
Ri = 1 K
Rs = 100 Ω
Rstr = 200 Ω
Vin = 5 V
2) Now, Rs = 105 Ω
The sensitivity is equal to:
