Help recognizing a Trident clone

[VapinSweetZ]

Hi guys, thanks for all the previous help, I really enjoy building my own coils and the flavor is amazing.

1. Just out of curiosity,
I have a Trident clone and I'm interested whos the manufacturer of it:
Looks exactly like this one: $16.47 Trident 24K Gold Plated Rebuildable Dripping Atomizer(RDA) at FastTech - Worldwide Free Shipping

The store sales person said its an EHPro, but it doesn't look like any of their Tridents from the pictures I saw, so I guess it's something else.

2. The first coil I made (with vapowire a1 30 awg) changed its resistance from 1.7ohm to 2.1ohm every time I touched it.
I eventually just made a new one for about 1.4ohm (that's anyway was my target) and it works great.

But I'm still interested to understand how the first coil changed its resistance even though the wire stayed in the same "condition" and the length stayed the same...

[Answered, thanks lordmage] 3. How do I calculate a total resistance of dual coils? (I just know how to calculate how much each one will be and I understand the total of them together will be much lower because it creates 2 conductivity "channels").


Thanks!

if both coils are the same wire wraps and spacing and are in series the resistance is half. if memory serves but it gets weird if you do parrell vs seris. this might help you Steam Engine | Vaping related calculators

Thanks! great calculator for dual coils

Actually, two coils of the same resistance in parallel gives you half the resistance. So two 3-ohm coils in parallel gives you 1.5-ohms. Resistance in series is additive, so the same two 3-ohm coils in series would total 6-ohms.

When building on an atomizer you are going to be using parallel resistance.
