For the op-amp in the voltage follower circuit in Figure P14.14, the openloop parameters are \(A_{O L}=5 \times 10^{3}, R_{i}=10 \mathrm{k} \Omega\), and \(R_{o}=1 \mathrm{k} \Omega\).

(a) Sketch the small-signal equivalent circuit.

(b) Determine the (i) closed-loop voltage gain \(v_{O} / v_{I}\) and (ii) output resistance \(R_{o f}\).
