I realize this is information that is not necessary for vaping, but it's just bugging me. I have one tank that has an element which offers .5 ohms of resistance and it vaporizes my favorite juice @ 32 watts dissipated. Another tank is at 1.5 ohms and does a similar job at 9 watts. Watts = I2R. Current through a coil produces heat. The current in the first tank should produce much greater heat than the second. What am I missing? Different coil metals used with different coefficients of heat per current conducted? I'm confused. It seems as if a sub ohm coil should require much less wattage to produce the same heat as a coil greater than an ohm. Sent from my iPad using The Vapor Talk mobile app

Late to chime in on this, but one of the least confusing ways to think about it that I have come across is the water pipe analogy. In this analogy you need think of the following: Say you have two pipes, one of them a .5 inch pipe and the other is a 1.5 inch pipe. Now say you have 100 gallons of water and you want to push 50 gallons of water through each pipe in exactly the same amount of time. For sake of argument, we'll say that amount of time is 10 seconds. With the smaller diameter of the .5 inch pipe it is going to take a lot more pressure to get the water through that pipe than it would through the 1.5 inch pipe. The same principle applies to coils. The .5 ohm coil requires a higher wattage to reach the same temperature than the 1.5 ohm coil. That is a very basic analogy and there is much more to it, but the main point of the analogy is to explain why a coil of a lower rating requires more power to function in a similar manner as a coil of a higher rating.

This is common with new vapers in my opinion because they hate to conserve energy. Haha The simplicity of it is that you are craving the big hit and you're simply burning out your coils prematurely but running them too high a wattage. Especially if it's true that you are using 80pg 20vg. You don't say watt your coil resistance is so it's hard to comment exactly on your power/wattage issue. You are transitioning from smoking to vaping and they are VERY different inspite if the fact that they look so similar. My advice is to lower your wattage to the most acceptable vapor production for YOU and learn and understand that you are getting your nicotine in a WAY different way thsn smoking. It just takes a little while to get used to it. It's going to cost you a little more to figure out. Ease up on the pedal a little and enjoy the experience and you'll make it.

Good point... and you can also score some freebies from your local Health Dept. Thanks to the don't-ask-don't-tell drug-guidelines, if you ask for some, they have to give them to you. Yes, they are usually just a bag full of 1ml syringes (and paperwork for rehab locations, etc.). You can keep the standard needles and grind them down, or do what I do and leave them with the receptionist And, if you know someone who works there, you can get them to toss in some additional sizes too, especially if you let them know you are using them to measure liquids accurately (and not get high)

@bebop Wonderful to hear! I'm an old person. Old people tell stories. It's just what we do. Kinda like a "kick stinkies" blog.

@Edna I use this Im not sure about it with apple https://e-liquid-recipes.com/
