If the ceramic capacitor is energized after breakdown, will the short-circuited place be blown to form an open circuit?
Breakdown occurs when the voltage strength exceeds the tolerance of the insulator. The current can be directly turned on regardless of the insulator and is short-circuited. Places that have been shorted by power may be blown if there is no protection circuit. It depends on whether the power supply can supply enough current, but also depends on the breakdown of the capacitor (the short-circuit resistance is relatively small).
The ceramic capacitor is equivalent to a short circuit after breakdown. When the capacitor is connected to the DC, it is regarded as an open circuit. When it is connected to the AC, it is regarded as a short circuit. The ceramic capacitor has a property of being straight and straight. The term "breakdown" is understood by the electrician to be short-circuited. The cause of breakdown is mainly due to the physical damage caused by the external voltage exceeding its nominal voltage.
When a destructive discharge occurs in a solid dielectric, it is called breakdown. At the time of breakdown, marks are left in the solid dielectric, and the solid dielectric loses insulation properties. When the insulation board breaks down, a hole is left in the cardboard. So the word breakdown is used in solid dielectrics.
