load:-alternating sinusoidal voltage of 1V(excitation along z-direction)
Piezoelectric crystal generates electrical signals when a time varying pressure / force is applied. You need to give a time varying force for getting a time varying signals and perhaps vice versa.
Dear Mr. Pandey,
Are you talking about the output load of a Piezoelectric ( such as BVD equivalent circuit) , you can assume the output load as Resistor (R).
