what do Vcc, Vdd, and Vss mean? When is the appropriate time to use each?
thanks

daviddoria said:so what are the 2 different things? like base, base? why isn't it just Vb?
daviddoria said:ok...
then i dont get why "voltage drain" is the +V, and "voltage source" is the ground....

that is precisely where i have become confused...
daviddoria said:ahhh i get it
so what about Vcc ? is it the same as voltage source? cause the collector on the transistor is the same as the source on a FET, so Vcc = Vss
correct?

Because on an 'N channel' FET (the most common type) the drain goes to positive, and the source goes to negative - so the drain is the equivilent of the collector, and the source the equivilent of the emitter.
