← ScienceWhich failure occurs when surge voltage exceeds capacitor dielectric rating?
A)Dielectric structure irreversible breakdown✓
B)Inductance dramatically limits current
C)ESR temporarily increases heating
D)Capacitance value proportionally decreases
💡 Explanation
Dielectric breakdown occurs because exceeding the capacitor's dielectric strength causes ionization within the insulator and an uncontrolled discharge; therefore, the dielectric structure experiences irreversible breakdown, rather than an incremental change capacitance because ionization pathway creation.
