Calculate Inductive reactance: 200mH, 50Hz, Ω
This calculation can calculate the inductive reactance X
_{L} of an inductor knowing its inductance and the frequency.
You can also calculate the inductance knowing the desired reactance and frequency, or calculate the frequency knowing the inductive reactance and inductance.
X
_{L} = 2 π f L

Some common standard frequencies:
Inductive reactance formula says:
•The inductive reactance (X
_{L}) of a 200mH (two hundred millihenrys) inductor at 50Hz (fifty hertz) is 62.8318530718Ω (sixtytwo point eight three one eight five three zero seven one eight ohms).
•For a 62.8318530718Ω (sixtytwo point eight three one eight five three zero seven one eight ohms) inductive reactance at 50Hz (fifty hertz), you need a 200mH (two hundred millihenrys) inductor.
•A 200mH (two hundred millihenrys) inductor would have a 62.8318530718Ω (sixtytwo point eight three one eight five three zero seven one eight ohms) reactance at 50Hz (fifty hertz) frequency.
