letter C

Capacitance The property of a circuit or device that allows it to store an electrical charge. The symbol for capacitance is “C.” The unit for capacitance is the farad.

Capacitive Proximity Switch A type of sensing switch that produces an electrostatic field to detect the presence of an object without touching the object.

Capacitive Reactance The opposition to alternating current resulting from circuit
capacitance. Capacitive reactance is inversely proportional to
frequency (f) and capacitance (C). The symbol for capacitive
reactance is “XC.” The unit for capacitive reactance is the ohm.

Capacitor A device manufactured to have a specific capacitance.
