Hi, this is not a homework. I need your help to understand basic concepts. I am learning by myself. In textbooks, I usually see the circuit used to make Ic -Vce characteristics. I see that there are no resistors at base and collector/emitter. What will happen if VBE is larger than 1V or more? Is the PN juction will break down? How about if the transistor in saturation? Then if this is ideal transistor Vce = 0 but it is also connected to a external battery VBE ≠ 0. I am totally confused. Please help.
