The correct answer is: C. Non saturation resistive region
A p-transistor is a type of transistor that uses a p-type semiconductor material. It is a three-terminal device, with the emitter, base, and collector terminals. The emitter and collector are connected to a power supply, and the base is connected to a control signal. When a small voltage is applied to the base, it causes a large current to flow between the emitter and collector. This is called the transistor’s gain.
The p-transistor can be used in two different modes: the linear region and the saturation region. In the linear region, the transistor acts like a variable resistor. The current through the transistor is proportional to the voltage applied to the base. This region is used for amplification and switching applications.
In the saturation region, the transistor is fully turned on. The current through the transistor is no longer proportional to the voltage applied to the base. This region is used for power applications.
If a p-transistor is conducting and has a small voltage between source and drain, then it is said to work in the non saturation resistive region. This is because the transistor is not fully turned on, and the current through it is proportional to the voltage applied to the base.
Here is a brief explanation of each option:
- A. Linear region. In the linear region, the transistor acts like a variable resistor. The current through the transistor is proportional to the voltage applied to the base. This region is used for amplification and switching applications.
- B. Saturation region. In the saturation region, the transistor is fully turned on. The current through the transistor is no longer proportional to the voltage applied to the base. This region is used for power applications.
- C. Non saturation resistive region. If a p-transistor is conducting and has a small voltage between source and drain, then it is said to work in the non saturation resistive region. This is because the transistor is not fully turned on, and the current through it is proportional to the voltage applied to the base.
- D. Cut-off region. In the cut-off region, the transistor is turned off. There is no current flowing through the transistor. This region is used for switching applications.
