Vaper's Brain Explodes Trying to Comprehend Ohms

[cmdebrecht]

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...

With vaping it's all about watts, the more watts you have the more vapor that gets produced.

The MT3's I've seen are 2.5 standard. If you want warmer vape go lower. Go back to where you got it from to see what the original ohm was for sure.

E / I * R

E = Voltage
I = Amperage
R = Resistance

If you increase the resistance with the same voltage, you will get less current (Amperage) flow. Your battery will last longer, because it is using less power.

If you decrease the resistance with the same voltage, you will get more current (Amperage) flow. Your battery will not last as long because it is using more power.

I = Amperage

If you increase the resistance with the same voltage, you will get less current (Amperage) flow. Your battery will last longer, because it is using less power.

If you decrease the resistance with the same voltage, you will INCREASE current (Amperage) flow. Your battery will not last as long because it is using more power.

Fixed that for you

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.

The Evod is a regulated 3.7v fixed voltage battery. It is made to drive Kanger Evod, PT, PT2 and MT3/S bottom coil clearos.

I have one that outperforms my Ego VV knockoff batteries that are supposed to deliver up to 4.2v.

Your stock 2.5 ohm heads may be just fine, but getting a few heads at lower resistance ratings might improve performance. Try it, and see.

 

[retired1]

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.

I hate math too. I find the below chart helpful in determining what ohm juice device to use. Find your voltage (3.7 volts at the top of the chart) and look at the green blocks in the chart. This is the recommend watts for that voltage. Then look to the left column and find the ohm that is within the green zone.

As you can see, most of your options are in the green zone already. If you want a warmer vape, go with the smaller number. If you prefer a cooler vape, choose a higher number in the green zone.

(sorry bad.)

Look. Think of it as the amount of clogging in a water pipe. The higher the #, the more clogged it is. The more clogged it is, the less flow.

In our case, it's flow of electricity and that equals the heat (roughly).

So ohms are a measure of resistance to the flow of electricity. The more resistance, the cooler the coil.

Ohms of 0 would be a dead-short.

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!

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?

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.

or
A battery is a bucket holding energy used to water a garden

Small hole = little trickle, takes a long time for water to run out, not alot of work can be done
Medium hole = moderate trickle, takes moderate time to empty, good pace at watering
Large hole = big flow, bucket empties quick, washes out the dirt or you have to run to not over water
no bottom in bucket = short...washes out dirt, washes out garden...battery gets hot 'splody 'splody

If you use lower voltage on lower ohm attomizers, would the battery life not last longer? Or is it the amps that are changing battery life? And lower ohm takes more amps?

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.

You have that backwards, lower resistance, more amperage is used, less battery life.
Examples in this instance, it's a 3.7v device, so no real change in the voltage until it's dead (keeping it simple for now)So,
1.7 ohms at 3.7v, that takes 2.18 amps and produces 8 watts of power.
2.2 ohms at 3.7v, that takes 1.68 amps and produces 6 watts of power.
2.5 ohms at 3.7v that takes 1.48 amps and produces 5.5 watts of power.

The lower the resistance, the more power that is produced and the more energy is needed to produce that power. Think of it this way, the closer you get to 0, the closer you are to putting a pair of pliers across both posts of your car battery!

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