Inductive Reactance (X L) Definition: Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of AC current. It is represented by (X L) and measured in ohms (Ω). Inductive reactance is mostly low for lower frequencies and high for higher frequencies. It is, however, negligible for steady DC current.

Capacitance is the ability of a component or system to store an electric charge. Resistance is the opposition to the flow of electric current in a component or system. Capacitance stores charge and opposes changes in voltage, causing a delay in current flow. Resistance limits the flow of current, reducing its magnitude.

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. Reactance is symbolized by the capital letter "X" and is measured in ohms just like resistance (R). Capacitive reactance can be calculated using this formula: X C = 1/(2πfC ...

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. Impedance is the Pythagorean sum of resistance and reactance.
