Question: How do you measure inductor current? Answer: Switched-mode power supplies commonly use inductors to temporarily store energy. In the evaluation of these power supplies, it’s often useful to ...
A decent current measurement sensor ought to be an essential part of every hacker’s workbench. One that is capable of measuring DC, as well as low and high frequencies with reasonable accuracy. And ...
Key considerations for using a low current source include the maximum current, minimum current, and step resolution; the output settling time required; and the level of voltage compliance needed. It ...
Today's SoCs (system on chip) have many modes of operation. Subsystems are shut down when not in use. When the entire SoC is in a “sleep” mode, many subsystems may be shut down or run on minimal power ...
From tiny, battery-powered tire-pressure sensors to multimegawatt wind turbines, the nature of today's electronics and the incessant drive to improve energy efficiency make energy measurement a hot ...
Presently, currents in high-voltage equipment are measured using bulky and heavy current transformers (CTs). These use the principle of electromagnetic induction to generate a small secondary current, ...
MEASURING live voltages and current in today's high-energy environments can result in a severe hazard to equipment and users if proper precautions are not applied. Given the risk of transients, surges ...
Electron transport in nanoscale structures is strongly influenced by the Coulomb interaction that gives rise to correlations in the stream of charges and leaves clear fingerprints in the fluctuations ...
Illustration of ions moving in water under strong confinement. Courtesy: T Mouterde, ENS By measuring how the electric current of an ionic fluid is generated by the flow of water through ...
Leakage current is one of the most stringent, yet telling, parameters of possible danger to patients or caregivers. It does not take much electric current flowing through the human body to cause harm.
KLAUS BOHNERT, RICHARD THOMAS, MICHAEL MENDIK – Current and voltage measurements are two key functions in the control and protection of electric power grids. Traditionally, they have been performed ...
