REACTIVE POWER – Applied Industrial Electricity
Inductive reactance is the opposition that an inductor offers to alternating current due to its phase-shifted storage and release of energy in its magnetic field. Reactance is symbolized by the
Calculating Inductance and Inductive Reactance
An inductive coil generates a self-induced electromotive force (emf) opposing the initial emf in response to an AC supply. This phenomenon, termed inductive reactance, imposes limitations on the flow of time-varying
Inductive Reactance and Capacitive Reactance
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 a property exhibited by an inductor, and inductive reactance exists based on the fact that an electric current produces a magnetic field around it. In the context of an AC circuit (although this concept applies any time current is changing), this magnetic field is constantly changing as a result of current that oscillates back and forth. It is this change in magnetic field that induces another electric current to flow in the same wire (counter-EMF), in a

Inductive Reactance and Capacitive Reactance
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
Resistance, Reactance and Impedance | Basic
The amount of electrical reactance offered by a capacitor or an inductor depends on the frequency of the applied signal. The faster the rate at which an AC signal oscillates back and forth, the more a reactive component tends to react to that
23.2: Reactance, Inductive and Capacitive
(X_L) is called the inductive reactance, because the inductor reacts to impede the current. (X_L) has units of ohms ((1, H = 1, Omega cdot s), so that frequency times inductance has units of (cycles/s)((Omega cdot s) =
6 FAQs about [Is inductive energy storage a reactance ]
What is inductive reactance?
Inductive reactance is the opposition that an inductor offers to alternating current due to its phase-shifted storage and release of energy in its magnetic field. Reactance is symbolized by the capital letter “X” and is measured in ohms just like resistance (R).
Does inductive reactance limit power capacity?
In electric power systems, inductive reactance (and capacitive reactance, however inductive reactance is more common) can limit the power capacity of an AC transmission line, because power is not completely transferred when voltage and current are out-of-phase (detailed above).
Why is all power in an inductor reactive?
All power in an inductance is reactive because it merely shuttles into and out of the inductor and never leaves the circuit. An inductor’s opposition to change in current is an opposition to alternating current in general, which is by definition always changing in instantaneous magnitude and direction.
How do inductor reactances work?
To be specific, reactance associated with an inductor is usually symbolized by the capital letter X with a letter L as a subscript, like this: X L. Since inductors drop voltage in proportion to the rate of current change, they will drop more voltage for faster-changing currents, and less voltage for slower-changing currents.
What is the difference between resistance and inductance?
While resistance is simply a form of electrical “friction” dissipating energy in the form of heat, inductance stores and releases energy by means of a magnetic field.
Are inductors purely reactive?
In an ideal case, an inductor acts as a purely reactive device. That is, its opposition to AC current is strictly based on inductive reaction to changes in current, and not electron friction as is the case with resistive components. However, inductors are not quite so pure in their reactive behavior.
