Let current through inductor be \$i=I\:sin (\omega\:t)\$, then voltage across will be \$v=L \:\dfrac{di}{dt}= I\: \omega L\: cos (\omega t)\$. The reactance is \$X_L =\dfrac{|v|}{|i|}=\omega L\$, where the magnitude signs indicate either amplitude or RMS value, as appropriate.
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)
1 paź 2020 · Inductive reactance is defined as the effect by which the current flow of an alternating current in an inductor is reduced. Any alternating current or changing current will get impeded due to the result of inductance associated with it.
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.
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.
22 wrz 2023 · The inductive reactance of an inductor increases as the frequency across it increases therefore inductive reactance is proportional to frequency ( X L α ƒ) as the back emf generated in the inductor is equal to its inductance multiplied by the rate of change of current in the inductor.
