I was told (in Britain) that when a bulb burned out, it was the back-emf in the coil that was responsible. Have't tried to verify this.It would store and release energy at the mains frequency (60 hz here in the states), but that has no effect on the lightbulb except to increase the impedance compared to a non-coiled filament.
Thank you.We're talking about why filaments are coiled and not straight lines and how that affects the operation of the light bulb
Heat and temperature are two different quantities - I can stick my hand in a 350 degree oven without injury, but I can't stick it in a 212 degree pot of boiling water. I wrote heat because I meant heat. That's all I meant.I don't know what you mean by this. Could you elaborate?
