It's time for electronics 101, and how it applies to PVs.

Current flow (measured in amps) is the movement of electrons through a conductor. These electrons are sent out by the power source (volts) to act as the workers, and resistance (measured in ohms) is in the path of current flow and will slow the electrons (workers) down. Power (measured in watts) is the measurement of work being performed in the circuit, and will always manifest itself in the form of heat (doesn't that sound like heating up an atomizer to you?). Of course too much heat (power/watts) will pop the atty.

Now for the math, and I promise it's not that complicated:

A physicist by the name of George Simon Ohm discovered that there is a tight relationship between voltage, current, and resistance. This relationship can be described and predicted by mathematics, which has become known as "Ohm's Law". The basic statement of this relationship is that voltage and current are directly proportional (when we increase voltage, current will increase as well), and that current and resistance are inversely proportional (when we increase resistance, current will decrease).
Voltage = current multiplied by resistance
Current = voltage divided by resistance
Resistance = voltage divided by current
Power = voltage multiplied by current

Now let's apply Ohm's Law to a PV:

A 3.7v device with a standard atty;
Voltage 3.7v divided by an atty that is 3ohms = 1.23amps
The heat produced by this is determined by the power in watts which is 3.7v multiplied by 1.23amps = 4.563watts
We know this works, and we can use these numbers to compare the performance of the other combinations.

A 3.7v device with a LR atty;
3.7v / 1.5ohms = 2.46amps
3.7v * 2.46amps = 9.126watts (remember, this is the heat)

A 5v device with a standard atty;
5v / 3ohms = 1.66amps
5v * 1.66amps = 8.33watts (remember, this is the heat)

A 5v device with a LR atty;
5v / 1.5ohms = 3.33amps
5v * 3.33amps = 16.66watts (remember, this is the heat.....POP)

A 6v device with a standard atty;
6v / 3ohms = 2amps
6v * 2amps = 12watts (remember, this is the heat...on the bourder of POP)

A 6v device with a HV atty;
6v / 4.3ohms = 1.395amps
6v * 1.395amps = 8.372watts (remember, this is the heat....is this really any better than a standard atty at 5v?)

My ohm values for the attys are approximate, but you get the picture. This really answers all the questions "will this work with this?", "will that work with that?". I also think that anyone dabbling in making their own mods should understand these basics when choosing components that will work well together, and avoid injury.

Hi,

I quit smoking tobacco in favor of Swedish snus about 3 and a half years ago, and was just recently introduced to vaping. I've had an Ego-C for a little over a week and really like it. This is the 2nd vape forum I've joined since then, as I confess to having become a wee bit obsessed about exploring everything happening in the world of PVs, even to the point of spending what little money I have fairly recklessly...

... In the last week I ordered a Provape-1 starter kit, a Vivi Nova and extra heads, a couple of RBAs for learning. These are on the way. I also purchased Boge LR510 cartos, one of which I'm vaping now on the Ego. And extra stuff: Type A attys, a drip head, both 1000mah and USB passthrough batteries. Not to mention a fairly hefty order of nicotine concentrate, tobbacco flavorings and dilutent along with bottles, medicine droppers, etc.

I'm staying away from VV for now and got the Provape-1 because it is universally acclaimed as extremely well-made, durable and safe, and comes with a lifetime guarantee. Both aesthetically and practically, I value technological simplcity over features, bells and whistles, and my long-term goal with this is to be able to vape simply, effectively, durably and cost-efficiently.

I just like tobacco flavor. There are flavorings called Real Cig, Turkish Blend, and French Pipe I've found from three different vendors which are very good, and I could juist stick with anyone of those and leave it at that. I may dink around a little bit with trying to come up with a DYI juice that tastes like a Camel Regular, but it's not a big deal...

...and that's my "howdy I'm new here" rant! Happy vaping!
