technician a says that two diodes are required for each stator winding lead.
technician b says that diodes change alternating current into direct current.
which technician is correct?
technician a only
technician b only
both technicians a and b
neither technician a nor b

Explanation:

• For each stator winding lead, two diodes (one for each half - cycle) are indeed required.
• Diodes are used in rectifier circuits (like in alternators) to convert alternating current (AC) to direct current (DC) through the process of rectification. When AC is applied to a diode - based rectifier, the diodes conduct only during the half - cycles when their polarity is forward - biased, effectively "chopping" the AC waveform to produce DC.

Answer:

Both technicians A and B
