Capacitive reactance is the opposition that a capacitor offers to alternating current due to its phase-shifted storage and release of energy in its electric field.

As a capacitor charges up in a DC circuit, the charges accumulating on the capacitor plates will begin to oppose the current flow until it reaches zero (see force between two charges)..
