Ohm readings................

[whipitup]

Be prepared for a long post!!

Just started winding my own coils and am a little confused with the results I'm getting.

I have 3 types of wire (got with a bought atty from the classies):

Ribbon.
Thin round wire.
Thicker round wire.

Now, for what I understand, the more coils the higher the resistance, so I figured using the thicker/ribbon wire would get a higher resistance for the same number of wraps as the thinner wire.

Not so it seems.

Is this something similar to doing a twisted coil?? - and a thicker cross sectional area of wire in fact gives a lower resistance?

What I'm finding is I'm running out of room on the coil to get enough wraps of the wire I have to get a high enough Ohm reading.



Or have I got all that completely wrong?

All the AGA attiesii have coiled are running at or around 1.5 Ohms and (in my head) that's to close to the cut off limit for my mod (although they are working just fine).

Thicker wire (ribbon) will present a lower resistance because there is more space for the current to travel through.
Think of water running down a canal. Make the canal bigger, more water can run through. Make it thinner, less can run through.
Use .2 wire and all will be well.

also what are you measuring the coils with?...if a device then fine but if a meter you need to take off the measurement of the probes themselves...usually .4-.5...mine arent brilliant at the mo but trying to get em neater is working a bit better...although i have to say since seeing your post on cartos roger im loving the agr at the mo and go another coming and may get a third so i can have 3 juices on the go...just waiting for the lr's to come

I lake the canal scenario James.........makes sense!

Trouble is, I don't know what wire I have to start with!!

Using the device.

I still like cartos, using one right now actually.............but I need to buy some more.

Just try the round stuff for now. You can work it out if you have a multimeter. Basically work out the resistance at a certain length and compare to wire information.
I found the same with ribbon, going to be easier on a Mechanical mod me thinks.

ive got a handful of lr's coming to make sure im right in what im doing/vaping....once there here ill have a better idea cos the sr's are only good on the vamo...got a gus coming so on this,udt and sigelei tele need lr's....also got an evic for a good price so will be seeing what thats like ...very very happy with the agr though

be careful with the ribbon Roger if you do not know what it is, you really need 0.4 or 0.3, if its 0.6 or 0.7 you will struggle to get above 1.1 Ohms as it will need at least 6 or 7 wraps.

Are you using a multi meter or just the mod to take readings, my advise even with a mod that gives readings grab a multi meter from B&Q a tenner for there own make, well worth having. I see too many ppl saying they don't even check and say ye 4-5 wraps never know what Ohm they are vaping at. play safe

I got one of these : http://www.madvapes.com/cartomizer-and-atomizer-ohm-meter.html to check the ohmage on self made coils. It checks the ohmage without actually sending enough power through the coil to make it 'glow'. I've found it very useful.
