← ScienceWhich outcome results when a high-voltage capacitor fails within an industrial power supply?
A)Destructive dielectric breakdown propagates rapidly✓
B)Gradual reduction in equivalent series resistance
C)Increased thermal runaway self-correction
D)Harmonic resonance dampens input rectifier load
💡 Explanation
When a capacitor fails due to excess voltage, dielectric breakdown occurs, therefore a conductive path forms, leading to rapid discharging and potential explosions rather than ESR reducing and the initial breakdown propagating to adjacent sections because of the weakened material.
