is there a formula for genesis rbas?

[funkpit]

I just got my aga-t today and my first coil reads 2.8 ohm which is fine for me. I used 4 wraps of 32 kanthal over 400 ss mesh.

I want to know what I would do to raise or lower my ohms

To raise your resistance, either add more wraps or go to a bigger wire. To reduce your resistance, you can remove wraps, use a smaller wire or 'twist' strands of your wire - 2 strands twisted will cut resistance in half, 3 strands will reduce to 1/3 of the original resistance.

Actually, it is opposite of this... I think what you meant was to use a higher or lower ga.# in these instances. If want to raise it you would go to a thinner wire, as in if you are using 32ga you would go to 34ga to raise the resistance with the same amount of coils. If you want to lower it you would need to go to 30ga wire, and so forth.... Not sure where you got the info on twisted wire, but I don't think from what I read it will cut resistance in half or a third.... I know some people use 32 or 34ga twisted to get the same resistances as you would get with say a 28ga piece of wire... That was my understanding anyway...

Resistance on twisted (what I've been using) is also determined by how tight the wires are twisted together. Or atleast that has seemed to be the case for me.

something is seriously wrong if you are getting 2.8 with 4 wraps of 32. you shouldn't be above 2.0 or so with that. but then again they are crap china atties so the internal resistance maybe that bad. on my zap(no insulator, fat wick) i get 1.4-1.5 with 3 wraps....2.8 just seems awefully high with 4 wraps

yeah sounds like a short there with that resistance.
my 4 wraps of 32 come out a 1.3-1.4 ohm

When you short to ground you basically lower the resistance to zero...
With 4 wraps I am at about 1.3 ohms. Both on my cobra and my aga. You should keep wrapping and youtube the drill bit method. It works very well.

i don't know if i meant short then, but if there were a spot of mesh that is unoxidised, and the wire touched it and made it part of the circut wouldn't that increase resistance?

no just the opposite....resistance would go down...that is why you get low ohm error message.

You must have an awfully fat wick. Is it a 3/4 or 4/5?

Loose coil wires?

 

[funkpit]

Sorry but I made a mistake when i said 32 kanthal, is't 34 gauge, and at 4 wraps im getting 2.2/2.3 ohms. I am using the drill bit method and it seems to be working well. At 34 gauge with 4 wraps would you say my ohms are still to high when reading 2.2/2.3?
