attie question

[lordylordy]

does the resistence of an attie lower as it nears the end of it life

[Chrissie]

Up to a week ago, I would have said "no" & that in fact the resistance gets higher towards the end of an attie's life. However, according to Trog in a thread on UKVapers, he has some atties behaving the opposite way round.

hmmm so the resistance is altered? ok thanks chrissie will order some new ones

I've seen both happen too, though by and large I would say that the resistance increases. The thinner the wire, the higher the resistance, that is a fact of Physics. As you ise an atomiser the heat causes the wire to get thinner and thinner, until eventually it breaks. If the resistance decreases, then there is a likelihood that there is a short of some form in the atty, so the circuit remains completed, but something else is in contact with the wire, causing the increase. I would bet that there is a mesh fragment that is coming into contact with the wire and causing a false resistance reading...

great post rawveg easy to understand thanks
