Chapter 2, Problem 2.13P

Consider the full−wave rectifier circuit in Figure 2.7 of the text. The output resistance is $R_L=125\Omega$ , each diode cut−in voltage is $V_{\gamma }=0.7\text{V}$ , and the frequency of the input signal is 60 Hz. A filter capacitor is connected in parallel with $R_L$ . The magnitude of the peak output voltage is to be 15 V and the ripple voltage is to be no more than 0.35 V. (a) Determine the rms value of ${\upsilon }_S$ and (b) the required value of the capacitor.
