← ScienceWhich outcome occurs during transient electromagnetic exposure of parallel transmission line?
A)Increased capacitive coupling induces ringing✓
B)Standing waves cause localized overheating
C)Dielectric breakdown creates a short
D)Skin effect diminishes total line capacity
💡 Explanation
Increased voltage induces capacitive coupling, because mutual capacitance results in charge oscillations during transient events; therefore, decaying oscillations called 'ringing' occur, rather than overheat(due to resistive loss), dielectric breakdown (from a steady state high voltage), or diminished capacity (steady state AC analysis).
