resistance and sub ohming

[hy_cupcakes]

Anyone thought about the increase in temperatures affect on resistance on a coil. Been reading my physics notes, and increasing in temperature, increases the resistance of a coil. So say you have a coil of .05 at 4.2 pushing 84 amps. Won't be in the "safe" zone of the Sony vtc's. But if the increase in temp is drastic which it is, then the amps will decrease exponentially. As a result, the longer we hold the fire button the safer we vape ? Of course not holding it till it discharges the whole battery. also the fact that theres internal resistance in the battery/cell, it will never really be able to have a pd of 4.2 volts
Also I'm not saying I vape at .05 ohms, I certainly don't, as there's always other variables to account for. But for you guys out there who do vape at those resistances, just a reassuring bit of info

or say you was vaping at .08 and it pushes 52.5 amps, this is within the pulse limits of the sony vtc's, but they claim this is a pulse limit, and can only can be held down for so long before it becomes dangerous. but according to my physics, the resistance will increase decreasing the amps, to probably where it was less than 30 amps, and it can be fired for longer ?

the resistance difference between kanthal at 0C and 1400C is 5% and scales pretty much linearly in between

oh, well that makes this statement irrelevant ahahha ! thought i got onto something there, cheers for the info
