By the use of which of the following m D.C. can be obtained from AC. ?
Correct answer: D. Any of the above
- A. Silicon diodes
- B. Mercury arc rectifier
- C. Motor generator set
- D. Any of the above
Explanation
Silicon diodes and mercury-arc rectifiers convert AC to DC directly, while a motor-generator set performs the conversion electromechanically. Therefore, each listed method can provide DC from AC.
