Explain about the inverse piezoelectric effect.
Inverse piezoelectric effect:
While an alternating e.m.f is applied to the opposed faces of a quartz or tourmaline crystal this undergoes contraction and expansion alternatively within the perpendicular direction. It is termed as inverse piezoelectric effect. It is made use of into the piezoelectric generator.
