Inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it and is similar to the opposition to direct current (DC) in a resistance.
22 wrz 2023 · The opposition to current flow through an AC Inductor is called Inductive Reactance and which depends lineally on the supply frequency. When connected to an AC supply, the current flowing through an inductive coil produces a self-induced emf opposing the emf that initially set up the current.

All impedances must be calculated in complex number form for these equations to work. Resonance. This equation applies to a non-resistive LC circuit.
Inductive reactance can be calculated using this formula: X L = 2πfL; The angular velocity of an AC circuit is another way of expressing its frequency, in units of electrical radians per second instead of cycles per second. It is symbolized by the lowercase Greek letter “omega,” or ω. Inductive reactance increases with increasing ...
The opposition of an inductor to a change in current is expressed as a type of AC resistance. Ohm’s law for an inductor is \[ I = \dfrac{V}{X_L},\] where \(V\) is the rms voltage across the inductor. \(X_L\) is defined to be the inductive reactance, given by \[X_L = 2\pi fL,\] with \(f\) the frequency of the AC voltage source in hertz.
In Chapter 10 we learned that changing magnetic flux can induce an emf according to Faraday’s law of induction. In particular, if a coil rotates in the presence of a magnetic field, the induced emf varies sinusoidally with time and leads to an alternating current (AC), and provides a source of AC power.
