Which outcome occurs when a high-frequency AC voltage is applied across a piezoelectric crystal with inherent capacitance?

💡 Explanation

When a high-frequency AC voltage is applied, converse piezoelectric effect causes the crystal to deform because of induced electric field and interact with its inherent capacitance, leading to mechanical oscillation nearing resonance. Therefore, mechanical resonance and vibration results, rather than other options needing extreme destructive conditions.
