32. If the input voltage to a voltage Tripler has an rms value of 12 V, the dc output voltage is approximately (a) 36 V – when looking at Figure 2-69 in conjunction with the explanation, the Section 2–1034. When a silicon diode is open, a DMM will generally indicate (b) OL – is a failed or open diode, and (a) 0 V if the diode has shorted [Floyd]. 36. If one of the diodes in a bridge full-wave rectifier opens, the output is (c) a half-wave rectified voltage – “An open diode in a full-wave bridge rectifier will produce the same symptomas in the center-tapped circuit, as shown in Figure 2–82. The open diode prevents current through RLduring half of the input voltage cycle. The result is half-wave rectification, which produces double the ripple voltage at 60 Hz” [Floyd].
