You mean *o*mitting.
@ryanc
I voted for the light emitting resistor, but after the fact realized that's just an incandescent light bulb -- and, as it turns out, the magic ingredient in Hewlett Packard's first product: a wave form synthesizer sold to Walt Disney Studios to be used in "Fantasia".
So I guess I voted wrong -- smoke emitting diodes are worse.
The usual solution to this problem is to enclose the light-emitting resistor in a glass envelope filled with either inert gas or vacuum.
LERs so enclosed will emit light for a surprisingly long time—hundreds of hours—before failing.
I was assuming both options were failure modes. A glass enclosed resistor is not a failure mode its an essential device for light switch raves.
All the same...
Can we have an "All Of The Above" option please? :D
@ryanc My favourite is the Light Emitting Diode emitting the wrong kind of light.
"That's a different colour. Oh."
@ryanc Explosively smoke emitting capacitor.
Followed by a rapid evacuation from the lab due to unexpected olfactory adventures.
For the skilled among us, accelerated by leveraging the impulse from the top of the cap.
Depends.
If it is a large, old Selenium diode, that is life-threatening hazmat smoke.
(Two of our Math/CS profs were working on an early computer several decades ago when the power-supply blew with their heads in proximity. They were treated and released, but the dangers of Selenium rectifiers was impressed upon them.)
(A few old AC/DC trolley power conversion stations have striped "Se" warning diamonds still.)
You can make some resistors emit light, and that's ok. Even their purpose.
But when smoke comes out, that's generally a bad day.
