Sir, I am a student of first year and first semester. I have a question pertaining to basic electronics. the question is: for a common emitter configuration, what is the explanation of the output characteristics graph? What is the explanation of the behavior in terms of the base current and collector current? Why is the shape of the graph the way it is? Why is the base current more than the given collector current for a given point and why is the current gain more than unity(one)?

By the way, One way of understanding the basic operation of a bipolar transistor is by looking at its \"Vce-Ic curves\", i.e., the plots of its collector current (Ic) versus the voltage (Vce) across its collector and emitter for different values of base current (Ib). These curves are derived from a transistor in common-emitter configuration, and basically describe the transistor\'s common-emitter output characteristics.
