What's a short?

What's a short, what causes a short, how can I fix it, and how can I keep my ohms steady on one number

"A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path, often where essentially no (or a very low) electrical impedance is encountered."

Also is slang for "I don't know what, but,something is fucked up with this electrical device"

when the positive and negative of the batteries are somehow touching WITHOUT the power flowing through the coil.

 

[CHIEFTANG]

Is this the reason the ohm readout on my mod is changing?

what mod? what build?

 

[CHIEFTANG]

I have an ipv4s with a royal hunter, 24g Clapton 7 wrap 25mm(I think is the size of the coil) and it's like .37 but it changes when I hit the fire button

I don't have that mod. are they Kanthal claptons? or stainless steel?

did you check the post screws? the 510?

 

[f1r3b1rd]

and what makes you think that is short?

 

[CHIEFTANG]

Idk I'm still learning. It's a kanthol Clapton. And whenever I build no matter what I do the ohms always jump around and it worries me. Just wondering if it has to do with the coils or something else

You need to re-tighten you leads if your coil has been adjusted or after pulsing the coil, the metal softens and the screws can back out...Also make sure you 510 pin is tightened and all other connections on the atomizer.

 

[f1r3b1rd]

well, "ohms jumping" is not a short, on a dna that ususally means that screws are loose. or a lead is not sat right. OR that the 510 is backing out of the atomizer for some reason.

edit: thank you, Ray

how much do the ohms jump by?
if it's like 0.37 to 0.35 then that's normal.

 

[CHIEFTANG]

Yeah, around like that, but it's gone up over time, is that normal?

ohms of the coil may change as you use them

 

[5150sick]

if it's jumping like 0.37 to 0.42 or something then theres a problem.
but if you put in the coil fresh and it was 0.35 and it's been a few weeks the coil may change in ohms by up to 0.05 or so.

Wire "deadens" as you use it, heating and cooling rapidly slowly wears the wire and it creates a more restrictive pathway for the amount of current flowing through it, this is what resistance is measured by and over use it may go up, usually its not very noticeable. If this is what your experiencing it will be in a variance of .01-.04 +/- from your original resistance load.

Loose connection at or in the posts or 510. A short would read NO resistance, possibly as no atomizer.

One of my leads was a little long, and it was touching the coil on the other side. After some adjustments the problem stopped and the ohms have not jumped since! Thanks for all the help everyone!

So then would this have been considered a short? Usually when something like this happens (usually on a 4 post build where i've got the coils tight to the center of the atty and cant quite trim the leads after their installed) that gap or hot spot between the two coils will heat up so fast I'll know somethings not right. I usually catch it well before getting to the wicking phase, but I'm just curious is this by definition considered a short circuit?
