This tutorial will showcase how inductance, capacitance and resistance affect alternating current. A circuit may have the alternating current through it and the voltage across it rising and failing ...

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 ...

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

There is a wide need for position, motion, and proximity sensing using low power for various applications. Capacitive, inductive, and Hall effect sensors are among the approaches for today’s low-power ...

The rotary inductive sensors utilize resistance inductive capacitance (RLC) measuring technology, rather than a traditional magnetic positioning element—delivering complete immunity to EMC ...

Faraday’s coil confirmed the connection between magnetism and electricity. This image, found on WikiMedia Commons, was originally published in Frederick Bedell’s “The Principles of the Transformer” ...

Legacy designs of variable frequency drives (VFDs) used optocouplers or pulse transformers for isolation and mated them together with gate driver ICs. A more integrated approach, though, uses ...
