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 ...

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 ...

An Apple patent application discovered on Thursday reveals that the company is actively investigating wireless charging for its line of portable devices, but proposes to use the technology in a ...

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 ...

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 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 ...

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 ...
