You have a 1 MHz sinusoidal voltage signal driven into a 5uF capacitor. You are measuring both the voltage and the current with an oscilloscope. What is the phase of the current in relation to the ...

A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...

Understanding RC circuits in your physics lab! 📊⚡ In this video, we’ll introduce you to the basics of using an oscilloscope to analyze Resistor-Capacitor (RC) circuits. Learn how to visualize voltage ...

Although shunt capacitors offer several advantages at all voltage levels, those advantages come at a price. Not only must you purchase, install, and maintain capacitor equipment, you must be able to ...

The first major performance item to review is large-signal load-transient response performance. Here, a large-signal phrase is used in contrast to a small-signal. A small-signal transient literally ...

In a previous article I demonstrated the additional distortion produced when using High-K ceramic capacitors in a system’s signal path [1]. The underlying mechanism causing this distortion is the ...

Capacitors give an opposing effect, so the electrical current leads the voltage by a quarter cycle. We never try to completely compensate the system to power factor 1.0, since the risk of ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal ...
