When an electric field is applied on a piece of a piezoelectric material, the dimension along the electric field direction will always change but the sign can be different.
Is that correct?
Homework Answers
When strong external filed is applied then microscopic dipole will align in the direction of field so piezoelectric material will have electric field in the direction of external electric field .
So its dimension does not change. Answer is incorrect
