Inductive Reactance Calculator

The inductive reactance calculator is a tool to calculate the reactance of the inductor. The reactance phenomenon happens with an alternating current. The inductive reactance of the inductor is zero for direct current. In other words, we can say that inductor easily pass the DC. In this article, we will discuss inductive reactance calculation and its formula.

What is a Inductive Reactance?

The property of the material that opposes the flow of electric current in the circuit is resistance. Its unit is the ohm(Ω). In a similar way, reactance is the property of the capacitance and reactance that oppose the flow of current. The unit of reactance is also Ohm(Ω). The reactance terminology is only applicable to the AC circuit. The circuit components, such as inductor and capacitor, offer reactance to alternating current. The reactance is the opposition offered to an electric current in the AC circuit.

The inductive reactance causes reactive current to flow in the AC circuit. The reactive current is a watt-less component of the AC circuit current.

relationship between impedance and reactance

The resistance of a pure inductor and capacitor is zero, hence the impedance of the pure inductor and capacitor have only the reactance parts. In this condition, the reactance of the inductor and capacitor is equal to the impedance of the inductor and capacitor.

How to calculate inductive reactance? Inductive reactance formula

The resistance opposes the flow of DC and AC current. However, the inductive reactance opposes the flow of alternating current. Also, this theory applies to the inductors connected in the series or parallel combinations in the AC circuit.

The main difference between AC and DC is that AC has finite frequency whereas DC has zero frequency. The reactance of the circuit components, such as the inductor and capacitor depends on the frequency. In other words, we can say that the reactance of the inductor and capacitor is frequency-dependent.

We can calculate the reactive inductance of the inductor using the following inductive reactance formula.

The reactance of the inductor is directly proportional to the frequency. Therefore, the reactance increase with an increase in frequency. As a result, the inductor provide more opposition to a higher frequency AC. Thus, the inductor offers higher reactance at a higher frequency.

The frequency of the direct current is zero because it is unidirectional. The inductor offers zero reactance to the DC ( f=0); therefore, the inductor behaves short circuit for DC.
