I need to know what the basics are for simple to-92 switching transistors.
Ie. On a NPN is the base always a positive voltage, is the emitter always grounded, and is does the collector always have plus voltage?
If those facts are true is a PNP just the opposite of an NPN? Negative signal on base, Negative voltage pulse on the emitter and the collector grounded?
