Electronics takes a lot of math. Once you’ve mastered all the algebra and calculus, though, it is sometimes a drag to go through the motions. It also can be error-prone. But these days, you have ...

An inductor's apparent inductance varies with the measurement method and frequency. William Hays, BH Electronics, Inc., Marshall, Minn. Inductors range from RF coils used in communications through ...

The world is moving toward greater use of power factor correction (PFC). Wild, Charles, Precision, Inc. - Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor ...

This Power Tip shows you how to do a quick conversion of parallel-to-series complex impedances (and vice versa). It also shows that a graphical representation of this transformation as a function of ...

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 ...

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 ...
