Question about adapters changing ohms (or ???)

[ddirtyvapes]

Okay, let me preface this by saying that while I know lots about my PV, I'm not great with the more "techy" details of ohms, wattage, etc. The extent of my knowledge is basically what ohm ratings are appropriate to use with what voltages, and how to calculate the amperage.

I recently purchased some Boge 2.8 ohm 808 cartomizers, which were new for me. I have a soft spot for LR cartos in general even though my ProVari is my main PV, but I figured restocking on some higher ohm cartos wasn't a bad idea and was eager to give something other than a 510 or 801 carto a spin. I'm really enjoying them, but I'm a little confused about what's going on with their resistance. I know that when I use any carto or atty on my ProVari for a while, the resistance can (or usually does?) go down. For example, after a long vaping session my 2.0 ohm IKV 306 was reading around 1.6-7 ohms instead. No big deal.

Now, this isn't a PROBLEM per se since I can obviously run my ProVari right up to 6v, but for some reason the two 808 cartos I've used so far have been registering at 3.2-3.3 ohms. That seems like a big difference from 2.8, especially since it's over and not under. Does anyone know why this might be? Despite my limited knowledge on the matter, I also realize that the adapter, which is just a little piece of metal, shouldn't change the ohm rating one way or another... should it? I just can't think of why this would be other than the fact I'm not using a native 808 connection, but again, limited knowledge. I also know ohm ratings can vary slightly from their marked resistance, but in my case I've never seen anything that strayed more than about .1 ohm from what I expected it to be, other than when the resistance drops after heavy use.

Fortunately, as I said, this isn't really an issue or anything. I'm just curious as to why this might be.

Thanks!

I am by no means an expert in electronics, nor PV's, however, I do have a lot of experience using 808 cartos with 510 adaptors. I do not like 510 cartos and use 808 cartos exclusively (when I am not using an atty). All of my devices have 510 connections so I am always using an adaptor when I am not using an atty.

I have not noticed any difference with or without the adaptor (ohms-wise).

I also just metered a volt 808 cartos both with and without the 510 adaptor, both metered out at 2.5 ohms.

Some metals are a better conductor than others. That's why you get those nice gold leads for your sound system.

The adapter could be raising the resistance a little but it shouldn't be much or noticeable. A wet atty/carto can also show slightyly higher ohms when measured as opposed to a dry one due to the juice.

Whether your cartos are out of spec (which is not uncommon at all, I've had several instances where mine varried more than that out of the box) or other factors are raising it a little can't really be said without testing the equipment before and after which you'd need a external meter for.

That's the great thing about VV, you don't have to worry about it. If your getting higher resistance to the atty just bump the voltage up to compensate.
