the question may look ridiculous since I'm not sure if the collector-emitter resistance exists or not. Here is a simple commom emitter circuit
As I learn that when the Vb increase that will make Ib increase so Ic must increase too. When Ic increase as there is Load Resistor but Vcc is constant and Ic = (Vcc-Vc)/RL (Load Resistor) then Vc must decrease and vice versa. That how common emitter work
Now, what I concern is the Voltage Drop between Vcc and Ground is constant as well as Load Resistor value. Suppose that there is not thing between Emitter and Ground that make Ve = 0 and Vb = 0.6-0.7 while Vc is much larger (that depend on load resistor). So, there must be something that wastes the energy to make Ve=0 that cause voltage drop between collector and emitter. Is there something act like varying resistor between collector and emitter to make that.
In other words, to make voltage drop between collector and emitter there must be something act like resistor between them, right? If no, what make the difference in voltage?
In other configuration does collector-emitter have resistance as well?
