Which end of the resistor is up?
About twenty years ago a fellow who wrote DIY articles for one of the
UK audio mags, maybe his name was Andy Bland, made a joke: "Which end of the resistor is positive?" The magazine got a lot of replies from people claiming to be qualified in electronics telling him which end of the resistor is positive... The internet is a *lot* like that. Except more so.

Which end of the resistor is up?
Andrew Jute McCoy, as the jurors in "Alice": blathered herein to see what it remembered of its name, lest it forget entirely before the end of the day. Peter Wieck Wyncote, PA |

Recently, on the forum where I moderate, a question was asked by some person that he "possibly damaged his DVD player by inserting the fuse the wrong way?"............. Turned out his player got hit with a thunderstrike, he replaced the blown fuse but it went out right away with a "POOF"! ;-) Some capacitors, on the other hand, *do* have a preferred direction (and I don't mean electrolytics). You'll notice on some foil caps that one end is branded with a line of some sort. That is the outer part of the foil, forming a kind of "screen" around the cap, and should be ground side in bypass situations, or connected to the side with the lowest impedance in coupling arrangements. -- "Due knot trussed yore spell chequer two fined awl miss steaks." |

Actually, it is also good practice to align resistors so that the tolerance bands all point in the same direction, so that they can be easily read without reorienting the board or whole heavy amp each time. -- Andre Jute |
