What is Normal Resistance, Low Resistance and High Resistance?

What is a suitable voltage to different resistance?


To understand Standard Resistance (Normal) (SR), Low Resistance (LR) and High Resistance (HR/HV) of an e-cig atomizer/cartomizer/clearomizer/glassomizer, it helps to be familiar with Ohms Law.  

 


• Watts = Volts X Volts / Ohms



•Amperes = Volts / Ohms


But watts and amps are not properties of clearomizers or batteries. They are derived from clearomizer resistance (measured in ohms) and battery voltage (measured, of course, in volts).




So we need to balance battery voltage with clearomizer resistance to get an ideal vape intensity (4-8 watts or so) without burning out the clearomizer. If the voltage is too low and/or the clearomizer resistance is too high (relative to each other), the watts are low and you get a poor vape (little throat hit, vapour, and flavour). On the other hand, if the voltage is too high and/or the clearomizer resistance is too low, the amps are high and you can burn out the clearomizer.


If Watts< 4.0, too low to power the coils effectively but will not hurt to try it.


If 4.0<Watts< 8.0, Safe to vape, can give you decent vape.


If Watts>8.0, May damage or burn out your coils,

(the above all depends on exactly what model you are using so its just a guide)


Enter any 2 known values and press "Calculate" to solve for the others. For example, an eGo having a rating of 3.7 volts AC and using a Clearo of 2.5 Ohms will draw 1.48 Amps and 5.476 watts. Usually, you can know the Voltage from the battery and the resistance from the clearomizer.


    Voltage (E) = Current (I) * Resistance (R)

    Power (watts) = Current Squared (I^2) * Resistance (R)

    Power = I*E = E^2 / R
