Subject: [Noob] A not gate with a transistor
Posted: 16 Nov 2012 09:13:49 pm (GMT -5)
Hello! I've been wanting to begin my adventure with electronics for a long time, and without thinking that much about it, i kickstarted it by choosing to build an ALU for mu project on physics. Its nothing to complicated, the logical part is allready done, but i didn't predict electronics would be this confusing.
I've been reading quite a lot about it but there are some things that i can't understand, and sadly my teacher doesn't know much besides what she is supposed to know, so i have nobody to ask.
To begin with i read this article:
http://www.dummies.com/how-to/content/electronics-projects-how-to-create-a-transistor-no.html
and i dont understand one thing. When the base of the transistor goes HIGH, it allows the current to flow through the transistor. This ground path through the transistor creates a shortcut that bypasses the output, which causes the output to go LOW.But what is the definition of a shortcut in this case? There are 2 available paths for the current, why doesn't it take the path with the diode or split between 2 paths?
I know this question may seem stiupid to you, but im completely new to electronics. All i know are basics of electricity, which is ohms law and couple others.
