Options
- AI_C against I_B at constant V_ BE
- BI_C against V_ EB at constant V_ CE
- CI_C against I_B at constant V_ CE
- DI_C against V_ CE at constant I_B
Correct answer
D. I_C against V_ CE at constant I_B
Step-by-step solution
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 ob
