Capacitive Reactance The opposition alternating current resulting from circuit
capacitance.
”The unit for capacitive reactance the ohm.
Capacitive Proximity Switch type sensing switch that produces electrostatic field to
detect the presence object without touching the object. Capacitive reactance inversely proportional to
frequency (f) and capacitance (C).
