1. Basic Positive Ground Question (score: 1): Author: Unknown; Date: Tue, 11 Nov 1997 16:49:59 -0800; I'm taking a class on electrical troubleshooting for work. The instructor asks which direction does electricity flow pos to neg or neg to pos? In my ignorance I pipe up with "both". I say I believe b; /html/triumphs/1997-11/msg00803.html (7,682 bytes)
2. Re: Basic Positive Ground Question (score: 1): Author: Unknown; Date: Tue, 11 Nov 1997 20:01:03 -0500; In actuality you were somewhat right. Electrons flow one way (from negative to positive). The "holes", or abscense of electrons, flow the other way. This is meaningful in semiconductor theory actuall; /html/triumphs/1997-11/msg00804.html (9,585 bytes)

Re: Basic Positive Ground Question (score: 1): Author: Unknown; Date: Wed, 12 Nov 1997 00:00:21 -0800; Joe, Everyone knows that diodes work because they use magic paint for the little bands on their cathode ends.
