So, how pronounced is this DC-filament effect? If I
collect
dead lightbulbs from my cars, should I see filaments with gaps
burned towards the ground end more often than not?
I have noticed that if a car lightbulb blows, it tends to part at the
bit where one "straight" bit of the filament goes into the helical part.
I think this may be more down to mechanical stress.
