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 ...

Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...

Growing concerns about energy efficiency have led to the development of electronics with higher power density. In grid-connected and industrial applications, such as AC motor control, uninterruptible ...

A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical ...

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 ...

Sometimes, it's necessary to make microvolt measurements in the presence of volts. For example, the need arose to measure the thermoelectric potentials in an RTD ...

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, ...
