Ohms Vs. Voltage

[mrmack00]

I wasn't sure where to post so I did in the "ask the veterans" but I figured since applies to VV, buzzpro, specifically, you folks could help.

I'm seriously considering a buzzpro and intend on vaping in The 4.4 -5.0 range as that is apparently a sweet spot for many but I'm confused about the resistance carto's to use.

1. Ive seen a website that suggests a general rule is higher voltage with higher ohm and lower voltage with lower ohm carto's. Why? Is it concern over sending too much power through low resistance burning too hot and ruining the carto?

2. Can you describe the effects of ohm and voltage combinations and how they affect the vape experience? What's hotter or colder or creates more or less vapor?

3. I was using mega 1.7 single coil carto's for my riva, but then told the 1.7's are only for 3.7 to 4 volts. It was suggested to me that if I intend on vaping at 4 to 5 volts a 1.5 dual coil would work.. Doesn't that contradict if the resistance is lower and I'm using Higher voltage? Does it have to do with each coil being 3 ohm perhaps (honestly I don't know if each coil is 3 ohm)

Thanks!!!!!

I'll explain as simply as possible. The thing that affects the way a PV vapes is wattage. Wattage is basically how hot the coil gets (like the filament in a light bulb). The level of wattage is determined by the formula: Voltage X Voltage divided by resistance = watts.
So, the higher the wattage the warmer the vapor. With high resistance attys you want to increase the voltage to get to the wattage you like. I prefer my vape between 8 and 9 watts, for example, so I use 2.5Ω cartos at 4.6 volts (4.6 X 4.6 = 21.16, 21.16 divided by 2.5 = 8.464 )
Lower resistance attys were developed to make low voltage devices seem more like higher voltage devices. If you have higher voltage you don't really need low resistance.
The more watts you produce the more drain there is on the batteries. A lower resistance on a small proprietary battery like a Riva or eGo can cause a higher draw of amps from the battery than it's designed for. It will make them drain faster for sure and may damage them in the long run.
Does that help at all?

In reference to the Dual Coil Cartos

Bare in mind that although the resistance states 1.6-1.7ohms your actually firing two 3.2-3.4 ohm coils. This means that the standard rules do not apply regarding voltage to an extent. You can use a higher voltage on a 1.6 ohm DC carto than you can a 1.6 ohm single coil. You WILL drain more battery but you will not burn the wick or filler because each coil produces lower wattage. Confused yet?

Completely confused! Actually, that info helps alot!!! Especially the formula for wattage and the difference between the dual cartos and single cartos. Very much appreciated!!! So If I do get the Buzz Pro, What's a good all around Carto Brand and resistance? Any recommendations?

That is the whole beauty of VV, you can set it to work at it's best with whatever resistance carto/atty you have at the time. Resistance can vary between them even when they come from the same box and resistance changes as they are used so you can adjust accordingly.

Read this thread and it should explain it in simple terms. http://www.e-cigarette-forum.com/forum/battery-issues/189736-lr-harder-batteries.html

Ohm's Law Calculator

Use this calculator IF you want to know what watts you are vaping at , the DC ( dual coil ) carts have 2 coils in parallel ( parallel resistance divides the power between the 2 coils ) so if you are running a DC at 10 watts it is 5 watts per coil this is why the DC carts like higher voltages and current .

More confused now LOL !

Excellent info e'body. Thanks!!! I've been trying to understand the formula too. This answered it. Getting a ******** in December and this will help when it comes to setting it up for the sweet spot.....and about 50mls of a yummy juice or two... or three....LOL!!

Thanks Mike....



I didn't want my "past" side to come out.....

This is probably a good thread to mention the max current draw, and max total watts, permitted on the Buzz Pro, and Infinity Pro, which determines the permitted max voltage for a given resistance carto or atty. (I don't have the numbers at my fingertips, since I'm a 3 - 3.4 ohm kind of guy, just want to mention that they could go here).

 

[BuzzKill]

The Pro series are basically a 15 watts device . Use the Ohms law calc. post above to figure out your wattage.

So it should be okay up to around a 1.5 ohm DC at 4.7V (3.1A, 14.7W). Cool -- I wasn't certain whether there were any current limits. I'm happy with my 8W most of the time, nice to know it can be pushed pretty hard.
