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 ...

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, ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...
