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 ...

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 ...

The content discusses the principles of capacitance, inductance, and resistance in electrical circuits, particularly in alternating current (AC) systems. It explains how capacitors and inductors ...

Electric circuits often consist of several elements, some combined in series and others in parallel. The methods used to analyze series and parallel circuits can be combined to analyze these ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...

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 ...

If you’ve ever dealt with RF circuits, you probably have run into Q — a dimensionless number that indicates the ratio of reactance to resistance. If you ever wanted to measure Q, you could do worse ...

When shopping for loudspeakers or headphones, most consumers don’t even look at the impedance of the products they are considering. Do they need to? What is Impedance? Glad you asked. Most consumers ...
