a. Consider the full-wave rectifier shown in Figure 10.27 on page 494, with a large smoothing capacitance placed in parallel with the load RL and Vm = 12 V. Assuming that the diodes are ideal, what is the approximate value of the load voltage? What peak inverse voltage (PIV) appears across the diodes?
b. Repeat for the full-wave bridge shown in Figure 10.28 on page 495.
