SUMMARY
The Early effect describes how the collector current in a common emitter circuit increases with rising collector-emitter (CE) voltage due to base-width modulation. It does not directly alter the base current; instead, it influences the forward gain of the transistor, which can subsequently affect both base and collector currents. Understanding this mechanism is crucial for accurate transistor behavior analysis in electronic circuits.
