Response to the following question:
Consider an npn transistor operated in the active mode and represented by the model of Fig. A. Let the transistor be connected as indicated by the equivalent circui shown in Fig. B. It is required to calculate the values of RB and RC that will establish a collector current IC of 0.5 mA and a collector-to-emitter voltage VCE of 1 V. The BJT is specified to have β=50 and IS = 5×10-15 A.
