← ScienceWhich consequence results when internal dielectric breakdown occurs in pulsed-power capacitor banks?
A)Increased equivalent series resistance (ESR)✓
B)Increased capacitance rating
C)Enhanced self-healing properties
D)Improved voltage hold-off capability
💡 Explanation
Dielectric breakdown causes carbon tracking. This reduces insulation, enabling current leakage via resistive paths known as Conductivity. Therefore, ESR rises because these paths increase energy dissipation; rather than enhance performance with higher capacitance or breakdown voltage.
