Explain VV and the Kick to me

[Xaiver]

My understanding of electrical engineering is limited to what I've learned while studying here.

The way that I've taken to understand it is that a Dual Coil only feeds 1/2 the power to each coil. 10 volts would be giving each coil 5. 5 volts on a 1.2 ohm coil would produce a different wattage than 10 volts, right? Wouldn't that then adjust the watts?

Through my trying to figure out what the hell all of this crap is, I've had to learn from second hand information. The same what that everyone here is doing, that leads to things that are probably wrong, due to deliberate misinformation or that they learned it wrong.

I think that the best way to do this would be to have someone write up how the science behind certain things work, and explain it that way, in a sort of info-for-dummies kind of thing. I haven't found one of those yet, so I have to do it the other way.

Please correct me if I'm wrong, though.

Edit: Sorry, that came off a little more hostile than I meant. It's frustrating to me that I spend hours and hours reading and trying to understand something, only to find out that my time could have been better spent licking the wall.

Hey Xaiver! Hang in there! You're doing great. It's hard and has a learning curve. But....it's fun! I like how you help people on this board...so be cool. No wall licking (unless you get that wallpaper from Charlie and the Chocolate Factory...)!

Basically, voltage is pressure. So... if you had a Y shaped pipe full of water at 30 psi it would be 30 psi at all 3 points in the Y (bottom and two tops).

Same with voltage. The two coils are still at 5 volts "of pressure". BUUUUUUTTTTT.... something must get divided, yes? It's the electrons. Some go left, some go right. So you need twice as many... Electron flow is Amps.

Also, from the devices perspective whatever you screw onto that connector is what it is powering. The device doesn't know how many coils are inside the atty. It's just powering a 1.25 ohm load at whatever volts it is set to. It could be a single 1.25 ohm coil or two 2.5 ohm coils.... the device can't tell.


Soooooo.... for example.......having two 3 ohm coils is like the "Y" situation above.... it needs twice the amps of a single coil... and has 1/2 the resistance of a single coil (because there are two "flow lanes"). The last/best example I saw of this was the milkshake example.

Suck a milkshake through a straw. High resistance (ohms). Suck through two straws at the same time...Better/more flow because there are two lanes. That would have half the resistance (ohms).

There are many tutorials on the web. May want to see what's in the stickies in the modder's section too. AND HANG IN THERE. KEEP HELPING! You're a good guy!

Where do you get that? The resitance doesn't change because it's dual coil. It's still 1.25 ohms and it still takes 28.8 watts to drive it at 6V. It's composed of two 2.5 ohm resistors in parallel but, that changes nothing about the resistance of the curcuit or the watts to drive it at a specific voltage.

He meant 15 watts per coil. So he was correct. Just left out the (assumed) "per coil". 15 watts being very hot...

...snip...
Anyhow, you said 1.25 ohms and 6 volts. That's 30 watts....Oops, you said dual coils. That's 15 watts. That's pretty hot, and above what most people will enjoy for a vape. If you like it though, more power to you.

Disagree ......... in part.

While you are asking the PV to deliver 28.8 watts, each coil is only receiving 14.4 watts.

However it would not vape the same as a single coil at 14.4 watts or 28.8 watts. Real life experience would be that the DCC would fall about half way between a single coil at the two wattages with how it vaped.

Thanks Atty. I've been having a rough week, so my tongue isn't as sugar coated as it normally is. I tend to take things with more hostility than is intended, and lash back at them.

My son is 7 months old now, cutting teeth, we're all sick here, and he's been a cranky little bugger...which makes momma and poppa into cranky people too.

Upon rereading my post was a little harsher than intended. Sorry.

It's funny when you read instead of hear people say things (or even see body lang.) ... I read what you wrote as more factual than anything else.

I did want to encourage Xaiver. FYI - I didn't mean to imply anything about your post in particular (other than clarification...he meant 15 watts per coil).

Take a bit of bourbon, triple sec, scotch on your finger,
rub it on his gums...then take a shot yourself..

(never let it be said ECF isn't a full service forum....)

Having had 3 generations of children to experiment on, an ice cube still works best.

We've got a couple of those liquid-filled teething rings that go in the freezer. He loves to chomp on them when his teeth are hurting. He's still cranky though, the cold only lasts for so long.

Hmm pretty cool. Thanks for the explaination. I may just have to pick up a kick. I don't mind lower wattage. If I can get away with 10 watts off a 18650 pushing 5 volts to a 1.25ohm DCT that would work pretty cool for me. Plus give me the extended battery life of an 18650 IMR versus stacked RCR123A's.

I just noticed this. The kick is limited to 10 watts. That will take 20 watts. The kick has other limitations like how much resistance it has to see to fire. About the only VV that might be able to do that reliably is the Vmax but, I think it has a 5.5V limitation. That's a really high voltage for that resistance. Do you like singed eyebrows?
