Inductive Reactance is defined as the opposition to current flow. It is the reaction of the inductor to the changing value of alternating current. To explain further, a back electromotive force (emf) ...

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, ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Many interesting technical characteristics of power systems result from their use of alternating current (a.c. or AC) instead of direct current. Power is a measure of energy per unit time. Power ...

The author is a consultant in Carterton, New Zealand. This follows up his December article “Tuned Bandpass Filter Is Solution to Backup STL.” Many years ago, the active whip antenna and the active ...
