Which unstable outcome most likely occurs when an unshielded, high-voltage capacitor assembly's stray capacitance oscillates?

A)Parasitic oscillations induce electromagnetic interference
B)Dielectric thermal runaway causes capacitor cracking
C)Electrolyte boiling quickly reduces capacitance
D)Arcing creates a conductive carbon path

💡 Explanation

Parasitic oscillations induce interference because stray capacitance resonates with trace inductance, creating unwanted radio frequency signals; therefore, EMI increases, rather than structural failures, because shielding suppresses arcing.
