Which outcome occurs when rapid capacitor discharge triggers a Metal-Oxide Varistor (MOV) failure in a surge protection circuit?

💡 Explanation

When rapid capacitor discharge causes excessive current that surpasses MOV energy ratings, thermal runaway occurs because resistive heating surpasses heat dissipation within the MOV pellets. Therefore, clamping voltage increases rather than decreasing; harmonic cancellation or power factor correction aren't directly affected.
