The inverting op-amp shown in Figure 9.9 has parameters \(R_{1}=25 \mathrm{k} \Omega\), \(R_{2}=100 \mathrm{k} \Omega\), and \(A_{o d}=5 \times 10^{3}\). The input voltage is from an ideal voltage source whose value is \(v_{I}=1.0000 \mathrm{~V}\).

(a) Calculate the closed-loop voltage gain.

(b) Determine the actual output voltage.

(c) What is the percentage difference between the actual output voltage and the ideal output voltage.

(d) What is the voltage at the inverting terminal of the op-amp?
