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 ...

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.

You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember, in a series ...

I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

While it's often best to call an electrician if you suspect you have a dangerous electrical issue, you can also safely diagnose many of those problems yourself with a multimeter, which is why it's ...

APDs (avalanche photodiodes) or APDs, are common components in laser-based fiber-optic systems for converting optical data into electrical form. The bias voltage and current measurement requirements ...

Monitoring the current taken by a mains-powered appliance can be a challenge. Here's an approach centered on Hall-effect sensors and current-sense transformers, which afford the galvanic isolation ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
