← ScienceWhich risk increases when pulsed electromagnetic fields drive a capacitive displacement sensor near saturation?
A)Phase shift signal distortion arises✓
B)Thermal runaway damages capacitance
C)Ohmic losses become significant
D)Electrostatic discharge induces latchup
💡 Explanation
Phase shift signal distortion arises because applying electromagnetic pulses stresses dielectric material generating additional polarization displacement current. Therefore, the distortion degrades signal fidelity rather than thermal/ohmic losses, because sensor capacitance is directly modulated.
