Inductance, Reactance, and Admittance Calculator

This online inductance, reactance, and admittance calculator helps to calculate the value of reactance XL (Ω) and inductive susceptance BL (m-mhos) of an inductor by entering the value of the inductance L (nH) and frequency of operation (GHz).

This online calculator also provides an additional calculator to calculate the value of the inductance (nH) and inductive susceptance BL (m-mhos) by entering the reactance value XL (Ω) and frequency of operation (GHz).

What is inductive reactance (XL)?

Inductive reactance is the opposition offered by the inductor in an AC circuit to the flow of ac current.

It is represented by (XL) and measured in ohms (Ω). Inductive reactance is mostly low for lower frequencies and high for higher frequencies. It is, however, negligible for steady DC current.

How to calculate inductive reactance?

The inductive reactance XL is calculated by using the following formula in an AC circuit.

XL = 2πFL in ohm

  • Where:
  • XL = Inductive reactance in ohm (Ω)
  • L = Inductance value of the inductor in nH (nanoHenry)
  • f = Operating frequency of AC circuit in GHz

What is admittance?

In an AC circuit, admittance is the measure of how easily a circuit or device allows the AC current flow. Admittance is the reciprocal of impedance Z. The admittance is represented by the letter “Y” and the unit of admittance is siemens (S) or mho (℧).

How to calculate the admittance?

Admittance is the reciprocal of impedance Z= R + jX.

i.e., Y= 1/Z = G + jB measured in siemens

  • Where:
  • Y = admittance of a circuit measured in mho
  • G = Conductance measured in mho
  • B = Susceptance measured in mho

The formula for calculate the inductive susceptance BL is: BL = 1/XL in mho
