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.
We have seen how capacitors and inductors respond to DC voltage when it is switched on and off. We will now explore how inductors and capacitors react to sinusoidal AC voltage. Inductors and Inductive Reactance. Suppose an inductor is connected directly to an AC voltage source, as shown in Figure 23.45. It is reasonable to assume negligible ...
Inductive reactance is proportional to the sinusoidal signal frequency and the inductance, which depends on the physical shape of the inductor: X L = ω L = 2 π f L {\displaystyle X_{L}=\omega L=2\pi fL} .
21 mar 2024 · Inductive reactance is the opposition that an inductor presents to the flow of alternating current (AC). It is calculated using the formula : X_L=2Pi f L
5 lis 2022 · The inductive reactance formula is: X_ {L} = 2πfL XL=2πfL. where: f f f is the frequency of the AC signal in hertz (Hz); L L L is the inductance in henries (H); and. X L X_ {L} XL is the inductive reactance. 💡 You can switch between units using the toggle feature next to each input in our inductive reactance calculator.
23 mar 2017 · Inductive reactance (XL) is a measure of the opposition to current flow in an inductive circuit. It is caused by the magnetic field that is generated around the conductor when current flows through it. The mathematical expression for inductive reactance is given by the following equation: XL = 2πfL. where: XL = inductive reactance (Ω)
