By the use of which of the following DC can be obtained from AC?
A)Silicon diodes
B)Mercury arc rectifier
C)Motor generator set
D)Any of the above

Question

Quizplus · Accepted Answer

All the options listed (Silicon diodes, Mercury arc rectifier, Motor generator set) are capable of converting AC (Alternating Current) to DC (Direct Current). Silicon diodes can rectify AC to DC by allowing current to flow in one direction only. Mercury arc rectifiers, an older technology, also convert AC to DC using a gas discharge principle. Motor-generator sets can mechanically convert AC to DC by using an AC motor to drive a DC generator.
