You have two fixed bias circuits connected for testing. They are identical except that one is biased with a separate VBB source and the other is biased with the base resistor connected to Vcc. Ammeters are connected to measure collector current in each circuit. You vary the Vcc supply voltage and observe that the collector current varies in one circuit, but not in the other. In which circuit does the collector current change? Explain your observation.
