Since I am new here, I keep saying Me, I, and I Used To, I hate people that say things like that. I used to hate myself, but I am much better, thank you! I've been online since 1981, and am just bumping to get my five posts in.
Here are some tips, for all the odd Electrical Thingies, that accompany this hobby. Here are some comparisons. We'll use water. Please do not mix your electrical gadgets, and water, yet they have some things in common.
Voltage = Water Pressure. Often expressed as "E" in the various formulae. If something expects to see a certain amount of Voltage/Water Pressure, that is a preferred range. If I operate my 19V laptop on 110V, I will let the magic smoke out, and it will never work again. This would compare to a blown atty, except the laptop is more expensive to replace.
Amperage = The Diameter Of the Water Pipe. Often expressed as "I". Amps can be thought of as the maximum volume of water or electricity that can be supplied, as the device (or my lawn sprinkler) demands. If I have a charger that can supply a maximum of 1 amp, it will charge my device faster than a charger than can supply 500 Ma (one half of one amp). If you go the other way, and the device tries to draw more volume of electrons (amps) than can be supplied, we will let out the magic smoke again. As expressed in terms of our PVs, they are teeny, tiny, subdivisions of an Ampere-Hour. This is a measurement of volume (of water, or electricity) over time.
The WikipediaGodz have a better explanation than I do, here.
Resistance = A Sponge Placed in The Water Pipe, to reduce the Voltage. Er, I mean Water Flow. Often expressed as "R".
The Variable Voltage variants on PV, are very good ways to keep the heat constant. That is what is really the best thing!
I am vaping with Ego/clone-ish things so far. I have dripped, I have smart carted, I have LR attys, there are syringes in the bathroom, I have a gallon jug of white vinegar, and I am using more napkins than I ever thought I would. I do not really care for tea, but have some of those pyramid tea-bags. I couldn't find MarineLand Rite-Size U, so I did pass on that. There was lots o' fluval @ Walmart, and other blue foam @ the pet stores, but I decided I was getting in over my head.
I am most glad that I found these things, and you, gentle ECF forum-ites. I have spent a month reading, and I have gained much knowledge from your/our collective wisdom!
