🔍 Key Concepts

• single-phase center-tap full-wave rectifier: how current normally flows through each diode during alternate half cycles • difference between a shorted diode and an open diode failure • relationship between AC input waveform and resulting DC output waveform when one path is no longer controlling/rectifying properly

💭 Think About

• Sketch the normal current paths for a healthy center-tap full-wave rectifier on positive and negative half cycles, then mark what happens if one diode becomes a short instead of a one-way valve. • Ask yourself: during the half cycle when the shorted diode is supposed to be reverse-biased, what does the transformer winding now see? How does that affect whether the remaining diode can still produce rectified DC? • Compare what the output would look like if one diode were open (no conduction) versus shorted (conduction both ways) and match those patterns to the choices.

✅ Before You Answer

• Verify what happens to the transformer secondary if one end is effectively shorted to the center tap through a failed diode. • Check whether the output can still be unidirectional (DC) or if it becomes effectively AC or zero because of the fault. • Confirm which of the listed waveforms (zero, half-wave DC, full-wave DC, or AC equal to input) is physically consistent with a short circuit on one half of the rectifier.
