DC Analysis of Transistor and DC Load Line
For the common emitter circuit shown below (see figure 1) the parameters are:
VBB = 4 V, RB = 220 k?, RC = 2 k?, VCC = 10 V, VBE(on) = 0.7 V, and ? = 200. Calculate the base current (IB), collector current (IC), emitter currents (IE), the VCE voltage and the transistor power dissipation (PT). Show all work.

- In the CC circuit shown in Figure 2, calculate the following:
- IB
- IE
- VCE
- VE
- VB. Take ? = 49 and VBE = 0.7 V.
