PNP vs NPN

I'm doing my level 2 heavy duty course right now, electronics section, instructor is talking about PNP vs npn transistors (I know they aren't relays, but they are similar in many ways) instructor says he has a very easy way to remember npn vs PNP, but can't tell us because it's offensive and he could get in a LOT of trouble... Does anyone have any idea what this method would be? I found a lot of things that say PNp means Pointing iN NPN means Not Pointing iN But this is bugging the whole class, as to what the "dirty" version is. Thanks!no signature needed

??? I was not taught that... I dont want to imagine an instructors take on a xistor.. xyzzy

Left off a word:    PNP = Pointing iN Please

Pnp means positive negative positive and npn negative positive negative and I am almost one hundred percent that this refers to the leads that come out of the bottom so the pnp would mean the first lead is positive and the middle lead is negative and the third lead is positive .and vise versa or the npn%Pattonz~pleasure~palace%

On a schematic diagram, the symbol for a transistor has an arrow on it. The arrow points to the negative junction. Symbol for npn symbol for pnp NPN not pointing in. The arrow points away from the center. PNP pointing in Please The arrow points to the center junction. (Known as the Base)
