Physics - Semiconductors Question with Solution | TestHub

In common emitter (CE) configuration, the input is applied between the base and emitter, and the output is taken across the collector and emitter.

The output characteristics of a transistor represent the variation of the output current with the output voltage, keeping the input current constant.

For a CE transistor, the output current is the collector current $I_C$, the output voltage is the collector-emitter voltage $V_{CE}$, and the input current is the base current $I_B$.

Therefore, the output characteristics are obtained by plotting $I_C$ against $V_{CE}$ at constant $I_B$.

Answer: $I_C$ against $V_{CE}$ at constant $I_B$
