Q. Certain crystals produces electric signals on application of pressure. This phenomena is called
A) Ferroelectricity
B) Ferrielectricity
C) Pyroelectricity
D) Piezoelectricity
Explanation
(d)
When polar crystal is subjected to a mechanical stress, electricity is produced-a case of piezoelectricity. Reversely, if electric field is applied, mechanical stress is developed. Piezoelectric crystal acts as a mechanical transduce
