We discussed in the previous tutorials the dielectric—the insulating material that prevents the two parallel conductive plates from touching each other. An electrical current flows when a voltage is ...

Scientists conducted a detailed investigation into how electrowetting modulates charge storage inside carbon nanopores.

According to precedence, MOSFET datasheets show output capacitance at a single measured voltage. While these values were good enough for relative comparison between products in the past, it is ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to ...
