← ScienceWhich consequence results when a piezoelectric sensor's poling fails?
A)Voltage output becomes non-linear
B)Resonance frequency drastically changes
C)Induced charge approaches zero✓
D)Capacitive impedance becomes purely resistive
💡 Explanation
Poling aligns domains; depolarization eliminates net dipole moment. Therefore, less mechanical stress causes minimal electric Polarization, because fewer aligned dipoles generate charge, rather than other circuit changes when charge is present.
