Vaper's Brain Explodes Trying to Comprehend Ohms

[sawlight]

Gotcha, I was just trying to add clarification to the thread with simple questinns

No problem! I'm with you, trying to keep it simple and minimize the calculations for the OP! But your question probably led into the OP's next question, so I could use the examples they gave to show why.

I'm with post number 8
try them all for 6 or 7 bucks then decide..

As simple as I can make this, I think the others have missed the 2nd grade part!

1.8, warmer vape, shorter battery life.
2.2, a slightly cooler vape, a little more battery life, a good compromise.
2.3, even cooler vape, but the best battery life.

Pick what you like, battery life or warmer vape, or somewhere in the middle. Is that easy enough?

Thank you! Thank you! You have expertly dumbed this down for me.

Glad to help.

Ok when i went to electronics school this is how my teach explained it to us. Imagine electricity is moving through the wires, like a football player running down the field. In this metaphor Ohms were like the defense men. So the more ohms the more defense men blocking the little men carrying electricity.

You had a smart teacher!

The great thing is, you don't need to know anything about ohm's to vape with what you are vaping. Just buy all three different heads and see which one you like best.

This......x1000

Try them all and see what YOU like.
There is no chart or calculation that can determine what's best for your taste buds.

 

[cmdebrecht]

Yep, I agree. And they are inexpensive enough that I can do that. At least now I know what to consider. Before all this helpful information I had absolutely no clue. Thank God for smart math and science types.m

True that, they do all the hard work so we don't have to. I've been successfully building coils/wicks for the last six months with no issues. I don't own an ohm, volt or wattage meter and the sum total knowledge I have learned about it is:

Thicker wire = More electricity
Wraps = More equals less

When you get to that point, just do what others have done and then add a wrap or remove a wrap until you get where the vape works for you.

(FYI, the "just do what others have done" style of learning DOES NOT apply to learning how to ride & jump a motorcycle. As soon as I could stay upright, I tried jumping a couple of buses. It did not end well. Apparently you aren't supposed to jump Harley Electra Glide touring bikes. That thing sank like a rock in the air. Thank goodness I didn't break my vaping hand and could stealth vape in the hospital after I woke up two months later. I did have to listen to my wife say "What a jackass" under her breath every night for 6 months and endure her putting up the video on Youtube with the title "Don't marry someone like this")

non changing voltage:increase in ohms=less current=less wattage= less vape.
non changing voltage:decrease in ohms=more current=more wattage=more vape.
non changing ohms:increase in voltage=more current=more wattage=more vape.
non changing ohms:decrease in voltage=less current=less wattage=less vape.

just to make your head feel better just remember its an inverse relationship.

The Evod is a regulated 3.7v fixed voltage battery

That's good to hear. I was eyeing up an Evod starter kit but I wasn't sure about the batteries. I don't need VV but I'm done with unregulated batteries.

 

[vjdossey]

I have read, re-read am, and read again several explanations of the science and math behind the mysterious Ohm with absolutely no success towards a clear understanding of the topic. And frankly I don't want to understand. I have had enough headaches already.

I have a basic Kanger evod batt. I am using the MT3 rebuildable bottom coil tanks. I want to order replacement parts but I see there are three different options; 1.8, 2.2, and 2.5 ohms.

I have a feeling that the numbers mean more/less vapor but they suck up battery power at different rates. Can somebody please give me a 2nd grade reading level explanation of what to expect from the various ohms, or if it even matters?
Thank you so much. I am going to take a few tylenol and rest with an ice pack on my head while I await a reply...

Omg! Couldn't of said it better. I want a twist or spinner but not sure which 'ohms' work best. Low voltage use high ohms or low ohms? High voltage with low or high ohms? Help!!! Have you figured it out yet? Any help appreciated!!!

 

[vjdossey]

The simple version is that the lower the ohms, the hotter the coil will be at the same voltage. If you have variable voltage (twist battery or something where you can change the voltage) the higher the voltage, the hotter the coil. The hotter the coil, the hotter the vapor (too hot and it burns). The hotter the vapor, the greater the flavor and throat hit. These are generalities, there are other factors but you asked for the simple version.

And then what if I use dual coils? Less chance to burn?

No I still haven't figured it out. I thought, for one fleeting moment, that I had finally grasped it, but it did not stick. I have since given up and will heretofore refer to sawlight's post #13.

For me less is more....less knowledge more brain cells.

 

[WCSR]

Ugh. Come on you guys. Stop tossing the math at him.

OP, a lower resistance head allows more power to flow through the coil which allows it to get hotter. This vaporizes the juice more aggressively resulting in more flavor (usually). A higher resistance head doesn't get as much power pushed to the coil, which results in a cooler coil, but longer battery life.

It's all personal preference.

Thank you. People throwing numbers at someone, is like someone writing in Aramaic.

OHM's law..E / I x R, Watts = V x I (and that is a simple single resistor circuit)

Now throw in micro circuits, capacitors, diodes, and logic gates

It just takes getting used to figuring out the math

Or you can get a VW rig, and let the circuitry do it for ya

Simple block diagram for the VAMO...the "Vamo control" is shown as "a block" because what it actually does thru schematics WOULD break your brain!

Variable Wattage is pretty much "autopilot" No matter what resistance of atty/carto/etc you put on it, the VW device will adjust the voltage to maintain the wattage.

And then what if I use dual coils? Less chance to burn?

Dual coils use two coils that are each twice the overall rated ohms. So a 1.5 ohm dual coil carto uses two 3.0 ohm coils. It's like trying to boil a pot of water on two burners set on low, instead of one burner set on high. You use more energy from your batter for the same result. Dual Coils really work best when they achieve a lower overall ohm rating than one can really achieve with a single coil...allowing the battery to flow as much current as possible through as much coil surface area.
