You are correct, microcoils are shorts. However the purpose of a tensioned microcoil is to create the optimal relationship of turns so that the wind can be uniformly oxidized. It's not, it will short. Just like a formed coil which can't reach the potential of a strained coil for uniformity. So it exhibits loss in the form of diffusion to air as res goes unpredictably higher. As I just commented on earlier on another thread the deficiency shows up in operation and not during preparation as you must use high voltage to finish forming a hand wind into close contact. When you're cookin' the wind into high-red yellow zone everything looks just dandy (including the leads on an overtightened coil). Even, balanced moderate strain's the ticket.
It applies to all that the more symmetrical in form and strain the wind the better the output…if it's a contact coil.
G'luck p3d.
Thanks for the input MacT. You now, every time I read another post of yours explaining the phenomenon I find out something new and understand a bit more the concept. That said, I think the gaps between my winds are so big that liquid isolates them from shorting too. Although I do get pops as I mentioned earlier and I can only suppose they are shorts where the winds are at closest contact. What is also curious to me, is that these pops happen most of the times at the first vape I take after a rest period. i.e when wire is cold
