← ScienceWhich outcome occurs when an abrupt current change stresses a long transmission line's capacitance?
A)Voltage ringing induces destructive oscillations✓
B)Harmonic resonance reduces system efficiency
C)Skin effect elevates conductor temperature
D)Dielectric breakdown initiates chain reactions
💡 Explanation
Voltage ringing occurs because rapid current changes excite the transmission line's distributed inductance and capacitance resonant circuit, leading to overvoltage and reflections; therefore, ringing dominates rather than harmonic effects under transient stresses specifically.
