Low impedance breakdown?

I have removed a paragraph referring to a supposed failure of the lumped element model for low impedance devices. Are there any references for such a phenomena? Tomer Ish Shalom 13:52, 30 November 2006 (UTC)[reply]

Lumped element is a finite element in space and time required to travel within a lumped element is considered negligible, whereas distributed element is infintesimal. I have corrected the definition. ooooooooooopppppppppppppppppppppssssssssssssssssss

Lumped-Element Models in Mechanical/Aerospace/...

Shouldn't there be some discussion of the use of lumped-element models in other engineering fields? I'm studying thermoacoustics right now, and I've seen many papers modeling fluid dynamics, etc. as lumped-element circuits (cf. [1], [2]). Robin Z (talk) 14:14, 21 November 2007 (UTC)[reply]

History of the Lumped Element Model

I think some discussion of how and why the LEM came to be would go well with this article, along with some discussion of its origins (i.e. did it come from Maxwell's equations under certain restrictions (no current build-up on elements, etc) or did it originate with Kirchoff or was it maybe even before Kirchoff and his laws? Also, this article is lacking any references. Maybe someone with knowledge in this area could expand it better than I. I've had a look around on the internet and in the few textbooks I have, but to no avail. 90.204.100.172 (talk) 10:31, 30 August 2009 (UTC)[reply]

I was appalling at Maths when I went to Uni to study Computer Science, so I had a real hard time with circuit theory. That's my background, now the question: Does the Hybrid Pi model of the transistor also fit into this article as an LEM? —Preceding unsigned comment added by H-b-g (talk • contribs) 19:53, 19 July 2010 (UTC)[reply]

The. Worst. Intro. Paragraph. Ever

Seriously. It couldn't be a more perfect example of abstract nonsense if it tried. Were you *trying* to win a prize? I'm reasonably sharp, but boy, oh, boy this had me totally stumped until I did a quick Google and turned up this eminently more reasonable explanation (for the electromagnetics aspect):

A section of a transmission line designed so that electrical or magnetic energy is concentrated in it at specified frequencies, and inductance or capacitance may therefore be regarded as concentrated in it, rather than distributed over the length of the line.

Compare and contrast with:

simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions

Please sort it out. It doesn't matter what the discipline may be; the opening paragraph is supposed to be digestible by anyone looking up a quick cross-reference. Blitterbug (talk) 21:07, 3 October 2011 (UTC)[reply]
