What will happen to an insulating medium if voltage more than the breakdown voltage is applied on it__________ ?
Correct answer: C. It will get punctured or cracked
- A. It will become magnetic
- B. It will melt
- C. It will get punctured or cracked
- D. Its molecular structure will get changed
Explanation
Applying a voltage above breakdown strength causes dielectric breakdown, which may puncture, crack, or otherwise permanently damage the insulating medium. Becoming magnetic is unrelated, while melting is not the defining result.
