Which mechanism causes increased dielectric breakdown when voltage rises sharply?

💡 Explanation

Electron avalanche multiplication rapidly increases free electrons within the dielectric because a high electric field accelerates them, initiating further ionization; therefore, breakdown occurs at lower voltages than expected rather than due to slower processes such as material fatigue.
