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.
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. Inductive reactance \(X_L\) has units of ohms and is greatest at high frequencies.
Inductive reactance is the opposition of inductor to alternating current AC, which depends on its frequency f and is measured in Ohm just like resistance. Inductive reactance is calculated using: X L = ωL = 2 π f L
Sep 22, 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.
The inductive reactance formula is: Inductive reactance (XL) : 2π f L. where f is the frequency of the alternating current measured in Hertz (hz) and L is the inductance measured in henry (h). It is proportional to the frequency of the current and hence inversely proportional to the Time. XL α f and XL α (1/T).
Inductive reactance is denoted as XL. The SI unit is the ohm. The formula for reactance is given as. X L = 2πfL. Where the frequency is f, L is the inductance and X L is the inductive reactance. Solved Examples. Example 1: An inductor of 2H is connected to a circuit at a frequency of 50Hz. Compute the inductive reactance of this circuit? Answer:
XL is called the inductive reactance, because the inductor reacts to impede the current. XL has units of ohms (1 H = 1 Ω ⋅ s, so that frequency times inductance has units of (cycles/s) (Ω ⋅ s)=Ω)), consistent with its role as an effective resistance.
