← ScienceWhich outcome occurs when a parallel-plate capacitor's dielectric material experiences dielectric breakdown?
A)Stored energy linearly decreases
B)Capacitance value irreversibly increases
C)Internal resistance abruptly decreases✓
D)Resonant frequency steadily increases
💡 Explanation
When dielectric breakdown occurs, the strong electric field exceeds the dielectric strength, causing ionization and forming a conductive path through the insulator. This causes the internal resistance to abruptly decrease because of the created conductive path across the plates. Therefore resistance decreases, rather than linear energy changes, capacitance increase or resonant frequency increase, because these require maintained functionality.
