Science

Which outcome occurs when a piezoelectric crystal coupled with a capacitor experiences cyclical mechanical stress, near resonance?

A)Accelerated crystal lattice dislocation formation
B)Increased impedance matches acoustic source
C)Charge amplification via mechanical resonance
D)Enhanced thermal conductivity across the crystal

💡 Explanation

The mechanical stress causes charge separation across the piezoelectric material. This displacement current charges the capacitor via mechanical resonance, magnifying voltage swings because the crystal oscillates optimally and charge accumulates, rather than dissipating immediately.
