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 ...

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 ...

Electricity is often one of the least visible elements of a shiny, state-of-the-art data center. Learn more about the power needed to keep that data center running. Like many IT departments, ...

There’s hardly any piece of test equipment more fundamental than a volt ohm meter. Today you’re likely to have a digital one, but for most of history, these devices had real needle meters. The ...

Have you ever wondered what makes a loudspeaker “difficult to drive”? Do you wonder what’s so special about an amplifier that is stable into a 4 ohm load? If these are the kinds of questions that ...

Most everyone that has ever purchased an external amplifier is at least familiar with the term voltage gain. Simply, it is the degree to which an amplifier actually ...

IT = CV is a very basic and useful relationship that all electronics students should master. It is akin to Ohm’s Law, but something I was never taught in tech school –I had to learn it myself much ...
