Science

Which outcome occurs when a strained piezoelectric crystal is mechanically vibrated near its resonant frequency?

A)Electrical energy harvests maximal voltage
B)Crystal fractures due to plastic deformation
C)Dielectric breakdown exceeds voltage limit
D)Crystal maintains fixed charge displacement

💡 Explanation

Electrical energy harvests maximal voltage because at resonance, the crystal vibrations greatly amplify the piezoelectric effect. The **piezoelectric effect** directly converts mechanical vibration to an electric potential; therefore voltage maximizes, rather than fracturing because stress doesn't exceed materials' limits.
