[amp_mcq option1=”Change in ICBO” option2=”Change in VCC” option3=”Change in the values of circuit resistance” option4=”None of the above” correct=”option1″]
The correct answer is: A. Change in ICBO
When the temperature changes, the operating point is shifted due to a change in the collector-emitter leakage current (ICBO). This is because the ICBO increases with temperature. The increase in ICBO causes the collector current (IC) to increase, which in turn causes the operating point to shift.
The other options are incorrect because:
- Option B: The collector supply voltage (VCC) does not change with temperature.
- Option C: The values of circuit resistance do not change with temperature.
- Option D: None of the above is the correct answer.
I hope this helps! Let me know if you have any other questions.
