Cut off point
Quiescent point
Saturation point
None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: B. Quiescent point.
The quiescent point (Q-point) is the steady-state operating point of a transistor amplifier. It is the point at which the transistor is biased so that it operates in the linear region. The Q-point is determined by the values of the bias resistors and the input signal.
The cut-off point is the point at which the transistor is turned off. The saturation point is the point at which the transistor is turned on.
Here is a more detailed explanation of each option:
- Cut-off point. The cut-off point is the point at which the transistor is turned off. This happens when the base-emitter voltage is below the threshold voltage. When the transistor is in cut-off, it acts like an open circuit.
- Saturation point. The saturation point is the point at which the transistor is turned on. This happens when the base-emitter voltage is above the saturation voltage. When the transistor is in saturation, it acts like a short circuit.
- Quiescent point. The quiescent point (Q-point) is the steady-state operating point of a transistor amplifier. It is the point at which the transistor is biased so that it operates in the linear region. The Q-point is determined by the values of the bias resistors and the input signal.
