Help!?!?

[Cray Clay]

I need to figure out how to do my ohms law calculations but I need help I'm clueless as to what to do also on a side note some one told me 5 volts should be 19watts but on my istick 50watt 5 volts says it's 43.3 watts what's going on?

Ohm's and Joule's Law Calculator

Type in two variables and hit calculate.

I have the istick 50w n 20 watts for me runs 4.2v
I use subtank mini for it. Idk who told u 5v wud b 19w but they must b vaping something other than nicotine or e-juice.I'm new to this but still tht 5v is not 19w.

~1.3 ohms at 19 watts is 5 volts.

Here's a calculator: Volts to watts (W) conversion calculator

You need two variables to calculate wattage. Knowing just the voltage isn't enough, you also need to know the resistance of your coil in ohms. By entering the resistance and voltage into the ohms law calculator, you can calculate wattage. At any given resistance and voltage, the wattage will always be the same..... that's the law! (ohm's law that is)
