Definition and determination of the series inductance of tunnel diodes

The definition of partial inductance in terms of the vector potential (e.g. in [1) implicitly introduces equivalent circuits, where the voltage

This I-Presentation is a short introduction to a new technique that will offer users of high voltage test equipment that have motors with high impedance to view better qualified information about DC

Evo, I cut and pasted the info below from the Emoteq Megaflux catalog (emoteq.com). It supports Guests' definition from above, and also includes a mechanical definition of a motors time constant. Electrical Time Constant (TE) is the ratio of inductance LM in Henries, to t...

The definition of inductance is in the equation: V = L di/dt The potential drop across the inductor is proportional to the current rate of change. Saying that the voltage leads the current, is a special case of the general statement in the frequency domain. If you don't understand that, plot a...

Reactance (by definition) is the imaginary part of the impedance "Z". Z=R+jX Where: Z is the impedance, R is the resistance j is √‾-1 and X is the reactance. the inductive part is already included in the Z part of the equation. Vector analysis will show you that the power l...

Over the years that I've worked in electronics, I've noticed several common misconceptions about the use of the word "ground." Some of these misconceptions comes from our desires to shorten nomenclature designations to fit the tiny box on our wiring documentation. A large part of the problem comes f...

When we talk electric power, we think in terms of load. We exercise energy on a load, which might be: pure resistive (like in a boiler resistance) inductive (as in an electric motor) and capacitive (some ultrasound generators). Applying the driving voltage on the load, there will be a certain...

Spectrum Advanced Speciality Products (SASP) has introduced a new range of film capacitors which offer low inductance levels.

High-definition colonoscopy is much more sensitive than standard colonoscopy in finding polyps that could morph into cancer, say researchers.

The OV9712 high-definition CMOS image sensor has been incorporated into Microsoft?s new LifeCam Cinema.

Plasmatech (UK) has launched a range of Plasma High Definition (PHD) torches in conjunction with ATTC.

The SCTE Cable-Tec Expo in Colorado, US, has seen electronic cable manufacturer PPC exhibit its new high-definition multimedia interface (HDMI) offering.
