dude, i mentioned this in the other thread. hahaha.
click here --> Ohm's Law Calculator
all you have to input is "Voltage" and "Resistance" - (the two things your 2-in-1 ohm meter tells you...i gotta get me one of those...)
to be safe, i always input "4.2" in the "Voltage" box.
Voltage is the output of a freshly charged battery with no voltage drop. BUT! i just remembered you have the 2 in 1 ohm/volt meter so you can be more precise when inputting voltage!
and next,
Resistance, which is, in your case, "0.5"
click "calculate" and the site/formula will tell you the ampere and wattage output.
i dont mean to be snide with my elaboration in this post. (hope you didnt take it that way)
just want to be precise with instructions to help clear up your confusion.
hope you figure it out!
thanks!!
but i decided to build a 1 ohm dual coil setup just to be safe. and the 2-in-1 ohm and voltage meter is awesome.
