Hello Eveyone, I know this is NEWBY question but you gotta start somewhere. So for you advanced digital devices people. if you can take a couple minutes out of your time it would be appriciated. Why Does amplification occur in transistors? I'm looking for the actual theory And if I hook up a AC signal generator to a circuit with resistors. Why would i use a resistor after the emmiter(After the resistor it grounds) Schematic included Come on somebody?!?!?!!?
