How do the collector and emitter terminals of a BJT operate when no power supply is present?
The resistors RL, R1, and R2 connect the output terminals, so if the input signal amplitude is small you'll read 0 V DC between them. If the input is strong you may see a DC offset due to rectification of the input by the b-c junction.
You'll also see some pass-through of the input AC signal. If the input amplitude is high enough to turn on the BJT's b-e and b-c junctions then you'll also see harmonics of the input at the output.
