← ScienceWhich outcome from sustained overload occurs when voltage exceeds a capacitor's dielectric limit?
A)Dielectric breakdown and arc formation✓
B)Increased equivalent series resistance (ESR)
C)Capacitance value shifts linearly
D)Electrolyte leakage due to thermal expansion
💡 Explanation
Dielectric breakdown melts paths, and the insulating layer gives way because the electric field exceeds withstanding capacity, resulting in uncontrolled current flow rather than electrolyte leak; therefore an arc forms rather than gradual degradation.
