Dielectric StrengthMediumQuestion 31556

Question

Dielectric strength of a material is the maximum electric field it can withstand without:
  1. A
    Polarising
  2. B
    Breaking down (sparking)
    Correct
  3. C
    Conducting
  4. D
    Changing permittivity

Correct answer

Breaking down (sparking)

Explanation

Above the dielectric strength (breakdown field), electrons are torn free and the material becomes conducting — this destroys the capacitor.
