Correct AnswerD. The inductance and capacitance of the system
Quick Explanation
After current interruption, energy exchange between system inductance and capacitance determines the transient restriking/recovery voltage. Consequently the rate of rise depends on both L and C, approximately through the natural frequency 1/√(LC). Hence option D.
Detailed Explanation
Correct Answer
D — The inductance and capacitance of the system
Concept and Reasoning
After current interruption, energy exchange between system inductance and capacitance determines the transient restriking/recovery voltage. Consequently the rate of rise depends on both L and C, approximately through the natural frequency 1/√(LC). Hence option D.
Calculation / Key Relation
ωn≈1/√(LC)
RRRV is governed by the system L-C transient
Exam Takeaway
RRRV is an LC transient phenomenon.
Common Mistake
Do not attribute RRRV to only inductance or only capacitance.
