⚡ Enter ArenaAn engineer designs a parallel-plate capacitor with a polymer dielectric. If an unexpectedly high voltage is applied, which outcome results from exceeding the dielectric strength?
A)Capacitance value significantly decreases
B)Stored charge remains unexpectedly constant
C)Internal resistance approaches zero ohms
D)Dielectric breakdown creates a conductive path✓
💡 Explanation
Dielectric breakdown occurs because the intense electric field exceeds the dielectric strength, ionizing the material and creating a conductive path. Therefore, the capacitor fails by shorting, rather than by changing capacitance or storing different charge.
