Bridgeless atomizer question

[Janusxvii]

As a result of my vaping at work, my boss recently switched to ecigs (eGo battery with a bridgeless atty). However, he came to me today asking for help since it wasn't working. After some trial and error I was able to rule that his atomizers are the problem (he had two with him). One of them was clearly dead since I couldn't hear it hissing when fired and was measuring around 1 Meg Ohm on the multimeter. The other one i'm a little less sure about. It hisses when fired but was measuring 28 Ohms and wasn't producing any vapor. I guess for all intents and purposes it is dead as well, i've just never encountered a scenario like this before. I've never used bridgeless atties myself (took a liking to clearomizers) so I was wondering if this was a common issue for them? He's already ordered some replacements so I'm asking mostly to expand my own knowledge.

28 ohms? I wonder if your DMM has a problem. You wouldn't hear any hissing with a 28 ohm atty on an ego battery. That would be producing under half a watt of energy.

Joye Ego batteries are PWM regulated to ~3.4v. Let's say you had your meter set wrong and that's supposed to be 2.8 ohms (?possible?). Even then, it's only producing 4 watts, but you would be able to hear it vaporizing juice. It just wouldn't produce very much vapor. ------> Your boss would be better served with a ~2.0 ohm atty which would be approaching 6 watts of power (a little less, but getting close to 6).

A bridgeless atty is electrically identical to one with a bridge. The bridge is not part of the circuit.

I hope that helps.

No, I can definitely confirm that it is accurately measuring 28 ohms. The reason I say this is because I have checked the resistance using two different DMM's (my personal one, and one at work). Both are auto-ranging and the one at work gets sent out to a calibration house annually. I definitely understand what you're saying though. I didn't think bridgeless attys were electrically any different than bridged ones but since I've never used bridgeless myself I wanted to double check. I still have it since he obviously has no use for a non-functioning atomizer so I think I'm going to try getting it opened without breaking it so I can physically see the coil when fired. This just doesn't make any sense to me. Thank you though for your help. You confirmed my belief that something is definitely not right here.

If it's bridgeless, then you should be able to see the coil without opening it. Looking down the drip-tip end of the atty, the coil should be exposed and completely visible right in the center. You should see some steel mesh around a ceramic cup. The coil should be right there in the middle of that cup.
