The phrase power factor frequently is used in the electrical and power electronics industry. For example, home, office, and industrial electrical equipment often is fitted with power factor-corrected ...

Here is a close look at the common- versus differential-mode voltage and instrumentation amplifier (IA) topologies.

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...

What do a Rogowski coil, a magnetic core, and a hall effect sensor have in common? They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage ...

In this article learn about options for measuring current in motor control applications, the strengths and challenges of these options, and how using precision current measurement can optimize the ...

Physicists have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an external ...

Researchers have developed a way to assess soil health by measuring the electric current produced by its tiniest microbes. They used a probe originally developed to measure the electrochemical signal ...
