Zâ‚— = 2Ï€fL
The inductor impedance calculator determines the impedance of an inductor from its inductance, L, and the frequency, f, of the signal applied to it. The calculation is based on the formula:
Xâ‚— = 2Ï€fL
To use the calculator, enter the inductance value and the signal frequency. The impedance is then calculated automatically and displayed in ohms (Ω).
Inductive impedance represents how strongly an inductor opposes the flow of an alternating signal. This impedance increases with frequency: higher-frequency signals encounter greater impedance, while lower-frequency signals experience less. As a result, increasing the frequency in the calculator increases the calculated impedance, and decreasing the frequency lowers it.
Inductance has the same effect. An inductor with a higher inductance produces a higher impedance at a given frequency, while a lower inductance results in a lower impedance.
