What Voltage and Resistance ??

[sej016]

I have posted this on other forums, so some of you may have seen it before. A common question often asked about what combination of voltage and resistance work together. This chart shows that in a graphic format.

THIS CHART REFERS PRIMARILY TO SINGLE COIL DEVICES.

DUAL COIL DEVICES HAVE THE POWER SHARED ACROSS TWO COILS (HALF EACH) AND WILL OPERATE WITHIN THE UPPER MARGINS TO GET NEARER 4W IN EACH COIL.

Always handy, especially for people who haven't seen it before #icon_thumbsup#

That's great thanks for posting it I've printed it off, it may help me with confusion and stop me asking what can I use on what

There's a more compact version by the way:

Power = (Voltage x Voltage) / Resistance

From the chart, it seems you should normally aim between 4 and 8 watts.

Agreed. A combination of research, empirical evidence and experimentation shows that (generally) less than 3.5W will produce inferior vapour and over 8W may just be too hot or burn things out. That's not to say you cannot necessarily go outside these limits by a small margin. That's up to you. It is just a guide...it's not definitive.

And I had to write "V squared" as I could not figure out how to get a superscript 2. >

Great Little chart very useful
