\(X_L\) is called the inductive reactance, because the inductor reacts to impede the current. \(X_L\) has units of ohms (\(1 \, H = 1 \, \Omega \cdot s\), so that frequency times inductance has units of (cycles/s)\((\Omega \cdot s) = \Omega\)), consistent with its role as an effective resistance.
Inductive reactance is the name given to the opposition to changing current flow. This impedance is measured in ohms. Learn more about inductive reactance and related solved examples.
Definition: Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of AC current. It is represented by (X L ) and measured in ohms (Ω). Inductive reactance is mostly low for lower frequencies and high for higher frequencies.
The Inductive Reactance Formula is as follows: 2 f L inductive reactance. Where f is the alternating current’s frequency, expressed in Hertz (hz), and L is the inductance, expressed in Henry. It is proportional to current frequency and so inversely proportional to time.
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 resistance, since in practice we can make the resistance of an inductor so small that it has a negligible effect on the circuit.
Inductive reactance is a quantity that represents the opposition that a given inductance presents to an ac current in a circuit, such as is shown in Figure 8.56. Like capacitive reactance, it is measured in ohms and depends upon the frequency of the applied ac voltage and the value of the inductor. Inductive reactance can be expressed as follows:
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.
