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 ...

Download this article in PDF format. A T-coil is a special form of an inductive peaking circuit that will extend an amplifier’s bandwidth and speed up the output signal rise-time. The circuit uses a ...

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 ...

Sometimes a coworker sees something on your desk, and they have to ask, “Where can I get one of those?” and that has to be one of the greatest compliments to a maker. [Greg Zumwalt] nailed it with his ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

How efficiently and effectively a workpiece is heated is determined by the induction coil. Induction coils are water-cooled copper conductors created from copper tubing which is readily formed into ...
