DC Discovery: Ic = max(ohms(Vc,Rc,Vbe,etc), beta times Ib) Previously I though Ic = beta Ib. By this simulation, I understand that this is true subjected to Ohms law, which overwrite the above eq. When that happened, the transistor is in saturated mode. AC Discovery: - Capacitor values are value important to output waveform. The best value is Csource = 1uF, Cemittor = 3 uF - The above good Capacitor values depend on AC frequency. Change the frequency, and good capacitor values change. Question: - How to choose the right C1,C2 values? - Why Iout = 0 Amp?
