SUMMARY
In AC analysis of common emitter amplifiers, the load resistor (RL) and collector resistor (RC) are treated as parallel components when calculating the output voltage (Vo) in response to changes in collector current (IC) due to input signal (isig). This approach is valid because, during AC analysis, the coupling capacitor (Cc2) is assumed to be a short circuit, creating a low impedance path between ground and Vcc. This assumption simplifies the analysis and accurately reflects the behavior of the circuit under AC conditions.
