Relation b/w elctrical resistance and stress-strain
My question is regrading a subtle observation that i made when i was straing at my "spring coil type" room heater. Accidently i pulled up some stands of heating coil spring to make them straight section (obviuosly when it was switched off). Then, when i passed current through it, after some time, i found that the straight section's color was less "red hot" than the other part of spring.
Does it has anything to do with change in electrical resistance with stress-strain.

More likely, this is because there is more cooling air flow around the length of straight wire than around the same length of "coiled up" wire.
