HELP!!! HOW DO i MAKE A 3 OHM COIL FOR A REBUILDABLE?
Hi I want to make a 3 ohm coil for a rebuildable and I want to know what kind of coil I need and how many wraps in the wick? thanks in advance every one.
Short explanation. Measure out a distance on a piece of nichrome wire that reads 3 ohms, cut that length, then wind the coils around a rod to fit the atomizer, leaving enough to insert into the connections. Ease the rod out and insert.
This thread has pictures and discussion and might give you some insight. The resistance of the coil is dependent on the gauge and length of the wire used to make the coil, since nichrome wire is inherently resistive to current flow. The number of wraps only aids in fitting in into a small space. Wraps around the wick are key to juice atomization. The number of wraps depends on the atomizer and the gauge of the wire you using. Smaller gauge wire - fewer wraps, larger wire - more wraps due to lower resistance per inch. It all depends on the space you have to work with in the atty.
On a 2mm dia wick each wrap is 3mm circumference, .12 inches. With 32g A1/1.1 ohm/in =.14 ohms per wrap.
On a 2.5mm dia wick each wrap is 5mm circumference, .20 inches. With 32g A1/1.1 ohm/in =.22 ohms per wrap
On a 3mm dia wick each wrap is 7mm circumference, .28 inches. With 32g A1/1.1 ohms/in =.30 ohms per wrap
Wraps have no significance unless you take in the diameter of the wick and the ohms per inch of the R wire.
My numbers above are rounded off but are close enough if you are not using a meter and actually measuring you wire.
