Impedance in inductors reflects how much the inductor resists the flow of AC current, due to its inductance. For an ideal inductor (one without any internal resistance), this impedance is purely reactive and depends on the frequency of the AC signal and the inductance of the inductor. In real-world applications, inductors also have internal resistance, adding complexity to the impedance calculation. This section explains the role and significance of an impedance of inductor calculator, which simplifies these calculations for both ideal and real inductors.
Formula of Impedance of Inductor Calculator
// For an ideal inductor: Z = X_L = 2πfL
Where Z is the impedance in ohms (Ω), f is the frequency in Hertz (Hz), L is the inductance in Henrys (H), and π is approximately 3.14159. For real inductors, which have internal resistance, the impedance calculation involves additional steps:
// For a real inductor: Z = sqrt(R^2 + X_L^2)
Here, R represents the internal resistance of the inductor. This section clearly defines each variable and walks through the calculation steps.
Table for General Terms or Calculator
| Inductance (L) | Frequency (f) | Impedance (Z) |
|---|---|---|
| 0.01 H | 60 Hz | 3.77 Ω |
| 0.01 H | 1 kHz | 62.83 Ω |
| 0.01 H | 10 kHz | 628.32 Ω |
| 0.1 H | 60 Hz | 37.70 Ω |
| 0.1 H | 1 kHz | 628.32 Ω |
| 0.1 H | 10 kHz | 6.28 kΩ |
This table is simplified and assumes ideal inductors for ease of understanding. The impedance (Z) values are calculated using the formula for an ideal inductor (Z = X_L = 2πfL), assuming no internal resistance.

Inductive reactance is part of an inductor’s impedance that resists the change in current flow, dependent on the frequency of the AC signal and the inductor’s inductance.
The impedance of an inductor increases with frequency, as the inductive reactance is directly proportional to the frequency of the AC current.
While ideal calculations assume no internal resistance, real-world applications must consider this factor to accurately predict circuit behavior.
