Reactance is the energy storage and discharge from capacitors and inductors, so no power is converted to another form. Reactive loads result in ''reactive'' power. Impedance is the overall opposition to current flow in an AC circuit, resulting in the ''apparent'' power loss.

When applied to electron beam devices and devices employing distributed nonlinear media, the variable parameter is equivalent to a reactance in the sense that it is associated with energy storage rather than energy dissipative properties of the beam or medium.
Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped.

Electrical reactance. In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance.

Impedance is a mixture of resistance and reactance, and is denoted by Z Z. This can be visualized as a series combination of a resistor and either a capacitor or an inductor.

The reactance is inductive if it releases energy in the form of a magnetic field. And the reactance is capacitive if it releases energy in the form of an electric field. As frequency increases, capacitive
