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 ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

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 ...

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 ...

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 ...

One of the backbones to the success of any automated process is the accuracy to which one can detect and measure the various elements involved. Whether the process requires precise measurement and ...
