The inverting op-amp circuit in Figure 9.9 has parameters \(R_{1}=20 \mathrm{k} \Omega\), \(R_{2}=200 \mathrm{k} \Omega\), and \(A_{o d}=5 \times 10^{4}\). The output voltage is \(v_{O}=-4.80 \mathrm{~V}\).

(a) Determine the closed-loop voltage gain.

(b) Find the input voltage.

(c) Determine the voltage at the inverting terminal of the op-amp.

(d) Using \(v_{I}\) from part (b), find the percent error in output voltage compared to the ideal value.
