Hey all! I'm an older guy working my way into electronics for kicks.
I'm having a heck of a time with my Transistors I bought from Radio Shack.
How do I know the "right" voltage to turn it fully "on"?
Transistor: 2n3904 (Datasheet)
It seems that voltage is running through from the Collector to the Emitter without the Base having power being applied to it.
Any reason why this would be?
Also, I want to be able to run a siren with a 12V DC supply with this same transistor - is that possible?
Sorry for the noob questions...
