Depends on what you are wrapping it around and amount of wraps as the total length of the wire is what gives you the resistance. I use a 1/16th inch drill bit with 32 gauge Kanthal, five wraps gives me about 1.8 ohms. I use cotton for a wick. If you are using a thicker mandrel (or wick material to wrap the coil around) you will get a higher ohm coil. To get a lower resistance with the same length of wire you would need to switch to a thicker (smaller gauge number) Kanthal..
Kanthal resistances:
Kanthal A-1 Wire Specs: (Ohms Per Inch)
•28 AWG- 0.439 Ohms/in, 0.0508 Diameter (in.)
•30 AWG- 0.696 Ohms/in, 0.0100 Diameter (in.)
•32 AWG- 1.091 Ohms/in, 0.0080 Diameter (in.)
•33 AWG- 1.383 Ohms/in, 0.0071 Diameter (in.)
•34 AWG- 1.758 Ohms/in, 0.0063 Diameter (in.)
