I understand ohms and the fact that it's a measurement of resistance lol. I said I didn't know how coil wrap affects resistance on certain builds and why some prefer more with this type wire and less with that type wire. Gauges and wire types and all are new on the rda front but basic knowledge of electronics and measurement I'm fully versed on. Love seeing all the combinations out there, just came here to find out what's what and most importantly, what's safe. And I'm definitely checking out a different shop!
