i'm going over the concepts on how your vape works. i'll show how the atomizer works just like water flowing through a hose.if you never built before, don't let this keep you from starting.you don't need you understand all of it. this is a dripper atomizer with 3 post. the center post connects to the positive sideof the battery and the other posts connect to thenegative side of the battery. since this is only a single coil build,we do not need to use the extra post. i'll draw this out in a diagram, so look something like this. when i pour water into the funnel,
a current water flows through. somethingsimilar happens when you turn on your vape. instead ofwater, a current electricity flows. water flow for example could bemeasured in gallons per minute, but electrical current is measured in amps. so when you say 'i' equals 2 amps,you're saying the current is flowing at a rate of 2 amps. whencurrent flows through the wire it causes friction and that frictionis what what generates the heat. power is the rate that the current isconverted to heat and this is measured in watts. why doesthe flow rate increase when i raise the hose?
it's because of the pressure difference.the higher the lower level the more pressure there will be. with the vape, voltage is electrical pressure. in simple terms voltage pushes occurring through the wire. whenyou raise the voltage, you raising the electrical pressure socurrent flow will increase and the power will increase. you can see thecoil is brighter at 6 volts versus 3 volts. the contrast is a little high, but it's more noticeable if you look at the reflection.
if we use a thinner hose the waterslows down. the same thing happens when you switch to a thinner wire, thecurrent has a hard time flowing. in other words, there's more resistanceagainst the current flow and resistance is measured in ohms. basically if you have a 28 gauge and 32 gauge wire with the same length, the thinner 32 gauge wire will have a high resistance. higher resistance translates to less current flow and lesspower. but what this also means is that you need less of the thinner wireto get the same resistance
as a thicker wire. even though the resistance, power, and current are all the same the same; the surface area, length, and diameter of the wire is different. so it affects the vape differently. this will need to be explained inanother tutorial. what we just went over about the relationship between current,voltage, and resistance is known as ohm's law. the equation is 'i' equals 'v' over 'r'. combined with thepower equation you can rearrange these equations tofind the values you want. more importantly it's used to calculate resistance limits forsub-ohm vaping and battery safety.
remember you do not need to memorize allthis to build, there are charts that can be used. we will cover this in the following tutorials.
