For each set of measured voltages at the points (1,2, and 3) indicated in Figure 1, determine if they are correct and if not, identify the most likely fault(s). State what you would do to correct the problem once it is isolated. The zener is rated at 12 V.

(a) V1 = 120 V rms, V2 = 30 V dc, V3 = 12 V dc,

---

(b) V1 = 120 V rms, V2 = 30 V dc, V3 = 30 V dc

---

(c) V1 = 0 V, V2 = 0 V, V3 = 0 V

---

(d) V1 = 120 V rms, V2 = 30 V peak full-wave 120 Hz, V3 = 12 V, 120 Hz pulsating voltage

---

(e) V1 = 120 V rms, V2 = 9 V, V3 = 0V
