Amperage measures the rate that current flows through an electrical circuit. If voltage is like water pressure, amperage is ...

Current-feedback amplifiers have a higher slew rate than do voltage-feedback amplifiers. As such, current-feedback amps can better solve high-speed problems than their voltage-feedback counterparts.

For more than a century, scientists have relied on separate tools to measure the three core building blocks of electricity: volts, ohms, and amps. Each describes a different piece of how electricity ...

In this week’s Gizmodo University: Discover Electronics, we’re diving headfirst into the principle theories of electronics. The second of four classes in this series, “Volts, Amps, and Ohms” is ...

Welcome back to our Tech Tip series! Today, we’ll review one of the most essential tools in every toolbox, a multimeter.

In one respect, voltage is like water: you don't appreciate its value until your supply runs low. Low-voltage systems, defined here as a single power supply less than 5 V, teach us to appreciate ...

Because of the shell arrangements of electrons in various atoms and molecules, some substances are quite good at allowing a few electrons to move about freely (e.g., copper, silver, gold, aluminum), ...

As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...

What does an instrumentation amplifier do? An instrumentation amplifier (also known as an in amp) measures small signals in the presence of a noisy environment. The noise generally is common-mode ...
