When a dielectric material placed in uniform electric field, which of the following option is NOT CORRECT:
- A The free movement of charges in a dielectric is not possible
- B The free movement of charges in a dielectric is possible
- C The external field induces dipole moment by stretching molecules of dielectrics
- D The external field induces dipole moment by re-orienting molecules of dielectrics
Answer & Solution
Correct Answer
(B) The free movement of charges in a dielectric is possible
Step-by-step Solution
Detailed explanation
Dielectrics are insulators where charges are bound to atoms or molecules and cannot move freely like they do in conductors. Instead, an external field causes polarization by either stretching molecules or re-orienting existing dipoles. B) The free movement of charges in a…
