The output resistance of the full-wave rectifier in Figure 2.6

(a) in the text is \(R=150 \Omega\). A filter capacitor is connected in parallel with \(R\). Assume \(V_{\gamma}=0.7 \mathrm{~V}\). The peak output voltage is to be \(12 \mathrm{~V}\) and the ripple voltage is to be no more than \(0.3 \mathrm{~V}\). The input frequency is \(60 \mathrm{~Hz}\).

(a) Determine the required rms value of \(v_{S}\).

(b) Determine the required filter capacitance value.

(c) Determine the peak current through each diode.
