HI, I am prety new to electronics and whatnot.... I have read all about transistors recently and learned a lot. From what I read, you apply current to the input, then when you apply current to the gate, it lets the input flow through the output. This was great so I went to radio shack and bought some to try and make simple logic gates. After messing around with them, I was getting bad results. Even when I dissconect the current from the input, the current from the gate flows out the output and turns my circuit on! This is not good since my and gate should only turn on when both transistors are on! I have tried both NPN and PNP and neither worked the way I expected! what am I doing wrong? -Thanks :x
