An op-amp is in an open-loop configuration as shown in Figure 9.2.

(a) If \(v_{1}=2.0010 \mathrm{~V}, v_{2}=2.000 \mathrm{~V}\), and \(A_{o d}=5 \times 10^{3}\), determine \(v_{O}\).

(b) If \(v_{2}=3.0025 \mathrm{~V}, v_{O}=-3.00 \mathrm{~V}\), and \(A_{o d}=2 \times 10^{4}\), what is \(v_{1}\) ?

(c) If \(v_{1}=-0.01 \mathrm{mV}, v_{2}=+0.01 \mathrm{mV}\), and \(v_{O}=1.80 \mathrm{~V}\), determine \(A_{o d}\).
