[amp_mcq option1=”Linear” option2=”Saturation” option3=”Non saturation” option4=”Cut-off” correct=”option2″]
The correct answer is: B. Saturation
An n-transistor is said to be in saturation when the voltage between the source and drain is large enough to cause the transistor to conduct heavily. In this region, the transistor acts like a closed switch, and the current through the transistor is almost independent of the base-emitter voltage.
The other options are incorrect because:
- A. Linear is the region where the transistor acts like an amplifier. In this region, the current through the transistor is proportional to the base-emitter voltage.
- C. Non saturation is the region where the transistor is not conducting at all. In this region, the current through the transistor is zero.
- D. Cut-off is the region where the transistor is conducting very little. In this region, the current through the transistor is very small.
I hope this helps! Let me know if you have any other questions.
