I have a shorted diode in my system and I cannot fix it on time to test. Are shorted diodes usually reliably 'short' or do they behave oddly under certain conditions? (Its okay if its short so long as it stays short...)

Folks,
I have some teflon that I'm trying to rid from a metal surface. I've tried everything from sandpaper to scraping it off with a soldering iron and wick. How can I dissolve this? Is there a clever way to clean up teflon from a metal surface? The surface is a screen/filter for...
This makes sense, yes. So if the :
rate of generation > rate of leakage
then that condition will persist until the > becomes =.
How do I calculate the leakage rate then, as a function of partial pressure (or rather, the pp difference inside-outside)? (Sorry, Im an EE, no background in this...
Hello All,
I'm faced with the following issue: I have some batterys in a box and these batterys release Hydrogen gas. I want to know, given the cracks and other tiny imperfections in the metal box's construction, how much Hydrogen will exit the box. In essence, if I know the generation rate...
I just came across a very neat nanotech approach to testing the hydrogen concentration in transformer oils. if you google for 'transformer oil' and 'nano' and 'palladium' you'll come to a link to a magazine article on the device. that magazine is what you're looking for.
aw heck, heres the...
I can see how that got annoying....
I'm using a little piezo accelerometer for looking at jolts to people's heads (the part was given to me). It has an input resistance of ~300ohm an output resistance of ~1kohm. I suppose I'll have to calibrate it against something prior to using. That...
Thanks folks (I wish there was a similar forum for biochemists!)
I'll be using a 30 awg wire, sorry for the confusion. I have space for 5-6 of them so I was thinking of either: 3 dc or 3 ac pairs, or one 3-phase set. What design issues should I be looking at? I would like to think of the...
Good morning all, great forum. Here's my question: I'd like to send power through a few 32 gauge wires for a distance of several thousand feet. How do I figure out the limit on how power-hungry my load can be (it'll be a sensor) and what is a good way to send this power? My background is...
