Answer & Explanation
Correct AnswerD. Both Statements are False.
Quick Explanation
In a parallel MTDC system all terminals operate at essentially the same DC voltage, so power rating is mainly reflected in current rating rather than valve-voltage rating. In a series MTDC system the same current flows through all terminals, so individual terminal power is mainly reflected in its voltage contribution rather than valve-current rating. Thus both printed statements are false, giving option D.
Formula / Key Relation
Parallel MTDC: common Vdc, variable Id; Series MTDC: common Id, variable Vdc
Detailed Explanation
Correct Answer
D — Both Statements are False.
Concept and Reasoning
In a parallel MTDC system all terminals operate at essentially the same DC voltage, so power rating is mainly reflected in current rating rather than valve-voltage rating. In a series MTDC system the same current flows through all terminals, so individual terminal power is mainly reflected in its voltage contribution rather than valve-current rating. Thus both printed statements are false, giving option D.
Calculation / Key Relation
Parallel MTDC: common Vdc, variable Id
Series MTDC: common Id, variable Vdc
Exam Takeaway
Parallel → common voltage; series → common current.
Common Mistake
Do not relate the common quantity to terminal power rating; the varying quantity carries the power difference.
Quick Trick
Parallel → common voltage; series → common current.
