Capacitor device manufactured have specific capacitance. May also used to
describe the processing circuits together with memory and
other circuits needed for processing information.The symbol for capacitive
reactance “XC.
.
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)
