Is it a genuine istick?
Never mind...I see it now! Sorry!! It's been one of those weeks.

Yeah, I'm not sure why the myVapors insignia is on there??

Point taken. I'm just curious because similar things, jumps from around 1.5 to 2.5,
have happened for me three times. Each time it was an eleaf coil that came with a GS* tank. I suspect, but don't know, that these were an early production run for which the two coils did not (by design or accident) have nearly the same resistance. Otherwise, if one coil failed, we would expect the remaining coil to be in the 2.8 to 3.2 range. These events suggest that the tolerance was much greater than +/- 0.2Ω.

What were you vaping it on? I find the iStick 30 ohm reader isn't that accurate. When the coil is dry it might read way up (a 2.1 ohm reading 3 ohms), when it gets wet goes to the rating or even below (1.6 or less) and my own coils premade go down before burning up. While on the rebuildables is often a loose connection that can be easily tightened.

Resistors in series-

The longer legs would give more resistance if they were not nr wire. Resistance in series is found by simply adding the resistors for a total. In parallel the formula is R1xR2/(R1+R2). If the resistors were made with equal values- 3x3+9, 3+3=6, 9/6=1.5. However 3.75x2.5=9.375, 3.75+2.5=6.25, 9.375/6.25=1.5 also.

Hope your Mom gets ok LVM

Okay, I literally have smoke coming out of my head from those equations.
And thank you.

Aaaaaaaaaaaaaaawwww!!!! Thank you Nanny.
My mom has been in the hospital following double bypass/valve replacement surgery. She's been having a rough go of it and has been in ICU for almost 2 weeks now. This past Friday, it was not looking so good and they had to put her back on the ventilator. So I've been kind of busy with that and trying to get some renovations done around my house.

I'm so sorry LVM, you are going through a lot right now. Many of us have been where you are right now, so if you need anything or just to talk, this is the place. I will be keeping positive thoughts for your mom and for you, too. Stay strong.

Thanks Nanny. I appreciate that.

Cool. Thanks Kiv! I was just curious. It's a pretty neat little mod! I'm vaping on an M at 4.1volts and I'm happy.
Tastes great!

As detailed in the original question, iStick 30w, GS Air Ms. Sure, the istick readings are normally, or often, off by 0.1 ohms...tending to read high. The coil was saturated, so the expectation should have been a lower reading. Yet, when it was reading 1.5 and apparently one of the coils failed, the reading went to 2.5. Katya and Bikenstein have given a good explanation, one that assumes the. original failed coil resistance was >3.5, assuming some inaccuracy in the mod's reading.
I popped a new coil—ft clone "Supreme"—in and it is reading 1.5.

LVM, I'll be sending lots of get well thoughts, lots of white light and blessing to you and your mom.

Warm regards to you, and best wishes for your mother's recovery.

Hang in there, LVM.

If you can correct the 30's ohm reader problem with tightening screws on an rba that should tell you that you could be getting resistance variation in the factory heads because the wire is only held in place by a grommet. Heat corrosion, liquid and wear can affect that type of connection easily. My 30w reads the same coil resistances as my SX Mini M class.

LVM, You and your Mother are in my thoughts and prayers.

GF, it's possible it was not a complete failure on one of the coils, just increased resistance...
Hence the math figuring it out would suck.
For less than a buck fiddy a piece, did you get your vapes worth?

Thank you everyone. I really appreciate all the support.
Just got word from my dad that it looks like they are going to have to do a tracheotomy now.

[Copy and paste from a previous discussion on the subject:]

As coils age, they have a tendency to change resistance--it can go up or down, depending on what's happening with that thin, fragile wire.

If your atty reads a very high resistance (K Ohms, M Ohms.. or infinite Ohms) then it is "open," which means that the coil is broken, which means it's dead.

If it isn't quite "open", or broken, yet, but reads substantially higher resistance than the stock numbers.... it is fixin' to go open--just as bad.

If you are getting very low resistance, less than .5Ω, a short is about to happen or has happened.

0Ω reading indicates a short.

With dual coils, if one coil pops, the resistance of your atty will double. So, with 1.5Ω dual coil atty, 3Ω (or thereabouts) reading indicates that one coil is dead and the other one is still alive and well.
