Inductive reactance is defined as positive, while capacitive reactance is negative. The reason for the sign change is how voltage and current are related in inductors and capacitors. Recall “ELI the ...

Where X L is inductive reactance (in ohms), f is frequency (in Hertz), and L is inductance (in Henries). Note that inductive reactance is directly proportional to frequency. As frequency increases, ...

Inductive reactance is found by the formula XL=2ΠfL. ... Use of a reactance chart or nomograph makes quick calculations and investigations of suitable values very simple during design.

In the December 2008 issue of EC&M, we talked about calculating the inductive reactance of conductors that are in close proximity to (or touching) one another.We also noted that the inductance and, as ...
