Which number of diodes does a basic three phase rectifier use?
Answer: D
Six diodes, three positive and three negative, form the full wave bridge. Many alternators add three smaller field diodes, giving nine in total, which makes the last option a genuine description of a common machine. Most errors here come from carrying across a result from a neighbouring case where it does not hold. A symptom that appears under one condition and not another is what narrows the diagnosis quickly. A single measurement chosen to respond to the one asymmetry beats several that respond to shared behaviour.
