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 ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

The MOSFET power switch is commonly the most vulnerable part of a new switched-mode high-power circuit. One threat for this device is exceeding the value of the maximum allowed pulse current. You ...

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 ...

For whatever reason, cell phone companies really don’t seem to care about giving you a good battery for your phone. Here’s a great hack if you happen to have a purse — turn it into an inductive ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Use of electromagnetic induction for cooking purposes is witnessing widespread uptake around the globe. The market for ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...
