When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true.

When an electric current passes through the body, it can cause three main effects: When it comes to current, DC becomes hazardous at around 130 milliamps (mA)—a seemingly small amount, especially ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

The war of the currents was fairly decisively won by AC. After all, whether you’ve got 110 V or 230 V coming out of your wall sockets, 50 Hz or 60 Hz, the whole world agrees that the frequency of ...

Allegro MicroSystems has integrated power, voltage and current monitoring into a single chip with reinforced isolation. Only a handful of resistors are needed to complete the high-voltage interface ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...
