Gee, I thought two coils in parallel would give him 2 coils with 1.8 ohms each. But it will double the current and watts.
If you're making the same resistor for a parallel circuit, you can just double the value of the overall resistance you want to have, so as long as they're the same..0.9= two 1.8 coils 0.8= two 1.6 coils.
If you want different sized coils, you'll need to know the formula...2 & 3 will be the two coils.
1/resistance= 1/2 + 1/3
1/resistance= 3/6 + 2/6
1/resistance= 5/6
1/resistance= 1/.8333
Resistance= 0.8333
Oh to edit I just click on my post...
Series you add the resistance. Parallel you hsve to find the reciprocal.
The surface area is increased. I've doubled power outputs on dual coils. I typically use 2.0 ohm singles, but I'll pick a 1.5 ohm dual coil over a 3 ohm single coil. I feel like I get a better throat hit, but it's not as cool as the single coil in 3 ohms. More surface area=more heat distribution.

If each coil you build is 1.6 ohms when they are hooked up it will be 0.8 ohms. This will all be determined by what gauge wire you use and how may wraps you do.
This is going to be much easier for you with smaller gauge wire (32ga takes fewer wraps than 28ga to obtain the same resistance).
