← ScienceWhich outcome occurs when a mechanically vibrating capacitor undergoes parametric resonance?
A)Voltage amplitude exponentially increases✓
B)Capacitance value stabilizes indefinitely
C)Mechanical oscillations dampen immediately
D)Dielectric breakdown threshold substantially increases
💡 Explanation
Voltage amplitude exponentially increases because parametric resonance amplifies oscillations when the driven frequency is approximately twice the natural frequency, a process called resonant frequency multiplication; therefore, the amplitude grows rather than stabilizing and damping because external energy input overcomes losses in dynamic resonant systems.
