Which outcome occurs when excessive voltage is applied to a parallel-plate capacitor?

A)Dielectric breakdown and current surge
B)Increased capacitance due to plate expansion
C)Reduced charge storage from electron saturation
D)Resonant frequency shift in AC circuits

💡 Explanation

When excessive voltage is applied, dielectric breakdown occurs because the electric field exceeds the dielectric strength of the material, causing it to ionize and creating a conductive path, resulting in a surge of current. Therefore dielectric breakdown results, rather than any capacitive effects and resonance shifts which need alternating current conditions.
