Which risk increases when RF heating raises temperature within a high-voltage capacitor?

A)Dielectric breakdown field strength falling
B)Equivalent series inductance increases rapidly
C)Skin effect decreases charge capacity
D)Corona discharge reduces plate conductivity

💡 Explanation

Rising temperatures increase the risk of dielectric breakdown because the thermal energy weakens the dielectric material; this reduces the material's breakdown field strength. Therefore, dielectric breakdown is more likely, rather than inductance increases or changes to conductivity arising primarily from the frequency effect.
