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 ...

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 ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

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 ...

How do those defibrillators you see on TV actually work? Surprise! Physics can explain! So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, ...

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 ...

Find a downloadable version of this story in pdf format at the end of the story. In any industry, there are applications whose failure could mean lost revenue and increased annoyance. In very few ...
