Materials and Components

Q1: Assertion (A): In ionic dielectrics, P = P_e + P_i. Reason (R): In ionic crystals, permanent electric dipole moment is zero.

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:A - Both A and R are true and R is correct explanation of A

In ionic dielectrics μ_p = ∑_i e_i r_i and P_o = 0. Therefore P = P_e + P_i.
