In the attached schematic: what is the purpose of the resistors and capacitors? I understand the transistor, but the other components are not referenced.
Like I said, stupid question…

R1 and R2 provide DC voltage to bias the base = Vbase = VCC x ( R2 / ( R1+R2 ) )
RL is the load and develops a signal voltage across it.
RE sets the DC emitter current = ( Vbase - 0.6V ) / RE
C1 blocks the DC voltage at the base from the source and provides a high pass filter.
CE bypasses RE to increase signal gain.
The divider DC current VCC/(R1+R2) should be much larger than the base current.
