Inductive reactance is a resistance by inductors to the change of current flow, and is dependent on the frequency at which the current oscillates. DC current flows in only one direction so an inductor's impedance remains the same.
The unit of measurement for inductive reactance (XL) is the ohm.
Inductive reactance is traditionally positive while capacitive reactance is traditionally negative. Those are the conventions used by electrical engineers and they are consistent with a time-dependency of exp(+jwt).
Inductive reactance, XL, in ohms, is given by:XL = 2 pi f Lwhere:f = frequency (Hz)L = inductance (H)
Inductive reactance does NOT have it own sign or symbol. Rather, it uses Ohms as a quantifier. But Capacitive reactance ALSO uses Ohms as a quantifier. Fortunately, 1 Ohm of Inductive reactance is cancelled by 1 Ohm of Capacitive reactance at the same frequency of measurement.
While it is true that an inductor opposes the flow of an alternating current, it does not necessarily 'block it'. The quantity that opposes the flow of an AC current is the inductor's inductive reactance, expressed in ohms. Inductive reactance is proportional to the frequency of the supply voltage and, at 50 or 60 Hz, the reactance of a transformer's winding is relatively low (although very much higher than its resistance) and, while this acts to limit the amount of current flow, it certainly doesn't act to block that flow.
Inductive reactance, as well as capacitive reactance, is measured in ohms.
The symbol for inductive reactance is XL.
Inductive reactance is commonly used in AC circuits to limit current flow, control voltage, and tune circuits to specific frequencies. It is essential in applications such as transformers, motors, generators, and inductors to manage the flow of alternating currents and maintain efficiency in power transmission. Additionally, inductive reactance plays a key role in filtering unwanted signals in electronic circuits.
Inductive reactance is directly proportional to frequency. This means that as the frequency of an AC circuit increases, the inductive reactance also increases. Conversely, as the frequency decreases, the inductive reactance decreases.

Inductive reactance case of ac) is equivalent to resistance (in case of dc) for inductors.So if resistance increases current decreasesas well as if inductive reactance increases current decreases
Actually they work fine for both AC and DC, its just that DC is the limiting case where the inductive reactance falls to zero and the capacitive reactance rises to infinity.The other limiting case is infinite frequency (but of course this is not reached in practice, but if it could they work fine too) where the inductive reactance rises to infinity and the capacitive reactance falls to zero.
The unit of measurement for inductive reactance (XL) is the ohm.
Inductive reactance does NOT have it own sign or symbol. Rather, it uses Ohms as a quantifier. But Capacitive reactance ALSO uses Ohms as a quantifier. Fortunately, 1 Ohm of Inductive reactance is cancelled by 1 Ohm of Capacitive reactance at the same frequency of measurement.
The property that limits the current flow in an inductor is called inductive reactance. Inductive reactance increases with frequency, causing the inductor to resist changes in current flow. This property is a crucial part of inductor behavior in AC circuits.
