Behaving like a current source means that change in load does not impact the current. This seems true for a BJT since the current depends on the base current in the active mode.
Behaving like voltage source means that the voltage applied on the load does not change but the current does. This seems true for the BJT in saturation since if we change the load e.g add another equal value resistor in parallel and the transistor gain parameter does not change since it is in saturation and its power dissipation limit is not violated, then in this example the collector current shall double.
Is this correct way of understanding how BJT behaves?
