← ScienceWhich outcome occurs when a capacitive proximity sensor detects a target?
A)Target material influences free capacitance✓
B)Supply voltage exceeds breakdown limit
C)Dielectric material reaches Curie point
D)Sensor coil achieves resonance frequency
💡 Explanation
Target presence near the electrodes alters the electric field, initiating capacitive sensing because the parasitic capacitance changes due to induced charge; therefore, capacitance changes signal target proximity, rather than other effects like breakdown or resonance.
