What Happens to Amplifier Gain When Connecting a Load?

Click For Summary
SUMMARY

Connecting a load to the output terminals of an amplifier affects both current gain and voltage gain, depending on the configuration used. In a common emitter configuration, the voltage gain decreases with the addition of a load due to the voltage divider effect. Conversely, in a common base configuration, the current gain remains relatively stable, but the voltage gain is influenced by the load impedance. Understanding these dynamics is crucial for optimizing amplifier performance in various applications.
