Hey new guy needs help (:

[InKeDupB]

Ok so im new to the moding on the vaping and im having trouble with learning the ohmz and knowing whaT St to go for.... ive looked up videos and i just dont get it lol... i have a k101 with an igo w4 and i started doing micro coil's with it and i had 28g wire on a 7 wrap.... but i saw on here using a 30g to wrap it 12 times to get it right ??? i have sony 18650 battery. and my ohmz reader is reading off 1.93 ??? IM LOST lol help ?? i attached an image

I'm not sure I can help, as you sound further along than me. I will say that the resistance in a length of wire depends on two things: the diameter of the wire (less diameter = higher resistance) and the overall length of the wire (longer = higher resistance).

So I guess it depends on what diameter thing you are winding your wire on. If you made 12 winds around a can of coke it's going to be just a little high (hehe). I guess you know all this though, and so you'll have to wait for the big guns to show up and learn ya.

28ga wire will be thicker than 30ga wire, so the thicker the wire, the lower the resistance.

Depending on your amp output of your battery, determines what resistance you need to run in order to vape safely.

You say you have a sony 18650 battery, do you know the model of the battery? It should be marked on the battery it self. Google this number and see what the amp rating is for the battery.

Once you have the amp rating for the battery, use ohms law to find the lowest resistance you can run safely. For example, if you have a 10amp battery, according to ohms law, you need to run no less than .6 ohms at 4.2 volts. This will give you a amp draw of 6amps. Even though you battery is rated for 10 in this case, I wouldn't push it past 60% of total amperage.

The thickness of the wire will determine how many wraps you need to get the correct resistance in your coil. The more wraps, the higher the resistance. Thinner wire will require less wraps to get a higher resistance (in theory). This isn't always the case.

So use this calculator Ohm's Law Calculator input you max battery voltage (4.1 - 4.2) and your measured coil resistance and you can find your current draw.

As your battery voltage goes down, so does the amp draw and the quality of your vape.

Always know your battery limits and check your coils at least once a day when you check your battery voltage if you running a mechanical mod to be safe.

Hope this helps clear it some

the picture is a little small to see the coils. However it looks like there is a fair amount of space between each wrap. With a microcoil you pretty much want the wraps to be touching each other, but not over lapping. Also since you are doing dual coils you individual resistance would be about 3.8ohm's on each coil. as the total overall resistance will be divided by the number of coils being used.

first thing you would want to do is figure out your target range of total resistance. then build each coil to double that resistance desired. here you can find the resistance by wire and length. Kanthal A1 Wire resistance Chart

I am running 2 1.2ohm 28 guage micro coils I think 6/7 wraps at .59 total. 7 wraps of 28 your doing seems high. If you touch the coils does it bounce the reading? If so make sure connections are tight.

Sony US18650VTC4 2100mah 30A Lithium Ion Battery 3.7v and my diameter is 1/8 of an inch with 7/8 wrap .. my ohmz reader on that read 1.53. and its the 28g kanthal a1 and yes when i touch it it jumps to higher ohms. yea i check to see if tightened down as well.. thanks guys for quick input. this stuff confusing lol. but trying to learn

i put in 3.7v 30amp. comes out on watts 111 and 0.12ohms wouldnt that be to low ????
