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 ...

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 ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

This Design Idea is able to turn off inductive loads at a very fast rate. When connected to a load (here 15mH + 10?), the modified freewheeling path in the clamping circuit based around M2 reduces the ...

IT was originally supposed that separating contacts in low-voltage, low-inductance circuits interrupted the current without arcing provided the supply voltage was lower than the ionization potential ...
