A) piezoelectric effect
B) anti-ferroelectric effect
C) ferroelectric effect
D) Pyro electric effect
Correct Answer: D
Solution :
Piezoelectric effect Certain crystal produce electric signals on application of pressure. This phenomenon is called piezoelectricity or piezoelectric effect. Ferroelectric effect In some crystals the dipoles are permanently aligned up even in the absence of electric field and the direction of polarisation can be changed by applying an electric field. This phenomenon is known as ferroelectricity or ferroelectric effect. Anti-ferroelectric effect In some crystals there is no net dipole moment inspire of the presence of small dipoles and therefore, they do not exhibit ferroelectric character. This phenomenon is known as anti-ferroelectricity or anti-ferroelectric effect. Pyroelectric effect Some of the polar crystals when heated produce electric current. This phenomenon is called pyroelectricity or pyroelectric effect.
