Ohms and watts?!?

[Yanu]

Hi,

Can somebody explain to me how to play around with the voltage of my ego c twist?
What I do is to go as high as I can before the burned taste arrives and then go back a bit. It kind of works but I'd like to know a bit more about it. Also, how do I choose the resistance? What do I get with lower, higher ohms?

Thanks

Low ohms (resistance) = less volta needed to fire the coil. The opposite goes for higher ohm. What it translates to is wattage. Lower watts is a cooler vape with less vapor. Higher watts is a hotter vape with more vapor production. The formula for that is (volts x volts/ohms). So if you are running say a 2.0ohm atty or carto at 3.7volts, you would be pulling around 7watts. Which is a nice cool vape for most people. I like to sit around 7.5-9 myself.

Here's a calculator if you wish to figure out the wattage seeing as the Twist only measures in volts:

Basically you're doing it right- different juices taste better at different volts. I've found 2.4 ohms gives the widest range with my Twist.

What he^^^ said +1.

Here's a handy-dandy chart that may help you out (not made by me, and I forget the member who deserves all the credit). It was immensely helpful for me; hopefully it can help clarify things for you as well

dang! i vape in the red (not the dark red) with 90% vg 10% pg

Now that you mention that, if I recall correctly the blog I first saw it in did mention that he kept the max recommended power a bit conservative since it was aimed at people who were newer to VV setups

that makes me feel a little better

That's the way I do it too.
The twist goes from 3.2 to 4.8 volts. If you find you can't go over 4V without getting a burnt taste, higher resistance (ohms) will give you more adjustment range.

For Those that like math:
Voltage is electrical pressure measured in Volts
Current is electrical flow measured in Amps
Resistance is opposition to current flow measured in Ohms
Power is the rate of work done measured in Watts (heat)

Ohms law:
Voltage = Current x Resistance (V = I*R)
Power = Current x Voltage (P = I*V)

Example:
Say you have a 1.8 ohm head and 4V gives you a burnt taste.
How much power is that?
V=I*R
I = V/R = 4V/1.8ohms = 2.22Amps

P = I*V = 2.22Amps*4V = 8.88 watts

What resistance would I need to not get that power until 4.8 Volts?
P = I*V
I = P/V = 8.88watts/4.8Volts = 1.85Amps

V = I*R
R = V/I = 4.8volts/1.85amps = 2.59ohms


Here's the 2 formulas (V = I*R) and (P = I*V) arranged in every way
