Which outcome occurs when rapid discharge happens in a high-voltage capacitor bank connected to an inductive load?

A)Overvoltage from parasitic inductance resonance
B)Thermal runaway resulting in capacitance drop
C)Electrolyte boiling due to joule heating
D)Dielectric breakdown decreasing stored energy

💡 Explanation

When a high-voltage capacitor bank discharges rapidly into an inductive load, parasitic inductance causes a resonance effect because the energy oscillates between the capacitor and inductor, resulting in overvoltage. Therefore, an overvoltage occurs, rather than, thermal runaway, electrolyte boiling, or dielectric breakdown which involve different failure types.
