510 Atty Resistance Drop

[breaktru]

One of my 510 attys that came with my TW Tornado started to diminish in performance. It produced less vapor. I measured the resistance and found that it dropped from the original 2.0 ohms to 1.5 ohms. I know it's life is about over but my question is: Why doesn't it produce more vapor at 1.5 ohms as does the 1.5 ohm LR's do?

No takers? No one want to take a crack at this post?

probably no takers because this is very weird.

P = (V^2)/R

Ohm's Law
V = IR

P = Power
V = Voltage
R = Resistance
I = Current

When one of these goes bad, the resistance increases due to 'gunk' building up on the coil and other componants. In order for Ohm's Law to hold true, given a relatively constant voltage and an increase in resistance, less current travels through the circuit. As this gunk builds, it becomes more difficult for current to pass through. Because the current has a harder time getting through the resistance the unit becomes hotter and hotter. Eventually, it becomes so hot that it pops and the resistance reaches infinity. So, no power is going through the circuit.

I have never heard of a normal atomizer's resistance decreasing during normal use. I have never heard of anythings resistance decreasing during normal use. And, i am dumbfounded on how such a thing can happen.

Are you sure you are reading your multimeter correctly? Is it possible someone put a LR atomizer into your PV without you knowing it?

I appreciate your response Willriker, Besides being a computer programmer/developer I have an electrical technology background. and yes I absolutely know how to read my meter correctly. I checked about a dozen or so attys. I know they are not mixed up because TW puts their logo on them and I have been exclusively using this ATTY ONLY.
I am stating my situation with a once 2.0 atty to a now 1.5. If it was an LR like my real LR, It would not give less performance. It has slowly started to diminish in vapor production.

I know your right, it is weird. Has anyone else experienced this?

 

[Willriker]

I'm still stumped. All i can think of is that, perhaps something is broken off inside of it. Meaning it use to be a part of the over all resistance of the unit, but now it isnt. You say that this atomizer has diminished in performance, So, perhaps something inside it is already broken off.

Thats the only thing i can think of to help you. Depending on what is broken off, It could explain why you are seeing a decrease in performance. It would also explain why the resistance has decreased, yet you arent getting the increased performance of a LR atty.

If you have extras, take it apart XD.

I bet you that something is broken inside of it.

Maybe a couple-three of the coil windings have become conductively connected/bridged by gunk or crap or who knows what, effectively paralleling some of the original coil resistance unto itself. Were this the case, it would vape less efficiently because of reduced active surface of the coil. Obviously just a guess. Autopsy required…
