The opposition, expressed in ohms, offered to the flow of an alternating current by capacitance. The symbol for capacitive reactance is XC.

The opposition to alternating current due to the capacitance of a capacitor, cable, or circuit.(Course Material/EddyCurrents/Instrumentation/impedanceplane.htm)(Course Material/EddyCurrents/Physics/impedance.htm)

in an AC circuit, the voltage across the capacitor divided by the current through the capacitor; analogous to resistance in a DC circuit(see equation 21.18)

Opposition of a capacitor, measured in ohms, to changes in voltage.

The opposition that a capacitor offers to a time changing signal or supplied voltage. Its value is XC = 1/2 fC

The opposition of a capacitor to sinusoidal current. The unit is the ohm.

Opposition to ac as a result of capacitance.

The opposition which a capacitor offers to ac for a given signal frequency.

The opposition to the flow of alternating or pulsating current by a capacitor measured in ohms. The imaginery component of the impedence of a capacitor.

The opposition to current flow provided by a capacitor. Capacitive reactance is measured in ohms and varies inversly with frequency.

The opposition to alternating current due to the capacitance of a capacitor, cable or circuit. It is measured in ohms and is equal to 1/6.28fC where f = frequency in Hz and C = capacitance in farads.
