We have gone full circle; LER is the new retronym for light bulb.
Without the bulb around it.
Incandescent lightbulbs are literally this.

Fair point! Any electrical component that is not a superconductor is technically a resistor in addition to whatever else it does.
Isn’t this a light bulb?
Once the smoke has cleared we check the connections we made earlier.
Everything is a light emitting resistor if you push enough power through it.

For those of you who would like to do stuff of this kind, here’s a video of Jeff Geerling showing how to use a microcontroller board and a power supply to blow up a capacitor! (He also shows a few other things you can do with microcontroller boards.) https://www.youtube.com/watch?v=Sd42q3OaOrE
I once discharged a 5 F capacitor into a 1 Ohm resistor.
It created an unpleasant smell on burning up.
Seems kinda hard on the PCB though.
But would be useful when you also want to desolder nearby components at the same time, so multipurpose.
