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 ...

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 ...

One of the most fundamental concepts in our profession is impedance. Due to the nuances of the mathematics related to this quantity, the minutia of what is taking place and the associated nomenclature ...

Last month, we clarified the definition of a vector and showed you how vectors are added, subtracted, multiplied, and divided. This month, we'll see how to use vectors in defining a complex circuit ...

In this article, we will explore AC analysis with the “.AC” directive, one of the main techniques for evaluating the frequency response of circuits. It is one of the most powerful features of SPICE ...

Many utilities have experienced how labor intensive it is to retrieve and compare power quality (PQ) data from numerous devices and systems, no matter the infrastructure in place. Delays and ...

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 ...

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 ...

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 ...

Bus bars are not typically viewed as cutting-edge technology but circuit designers can take advantage multi-layer bus bar configurations. Regardless of a bus bar’s size or complexity, its fundamental ...
