What does the term "Junction Field Effect Transistor" (JFET) refer to?
A type of bipolar junction transistor
A type of field-effect transistor that uses a junction to control current
A type of resistor used in circuits
A type of capacitor used in electronic devices
In a JFET, what is the primary function of the gate terminal?
To supply power to the transistor
To control the flow of current between the source and drain
To connect the transistor to the ground
To amplify the input signal
If the gate-source voltage (Vgs) of a JFET is increased, what effect does it have on the drain current (Id)?
The drain current decreases
The drain current remains constant
The drain current increases until a certain point
The drain current becomes zero
Which of the following statements is true regarding the operation of a JFET?
It operates in the active region when Vgs is greater than the threshold voltage.
It is always in the cutoff region when Vgs is zero.
It can be used as a switch when Vgs is less than the threshold voltage.
It allows current to flow freely between the source and drain when Vgs is negative.
What is the main advantage of using a JFET over a bipolar junction transistor (BJT)?
JFETs have higher current gain than BJTs.
JFETs are less sensitive to temperature changes.
JFETs can operate at higher frequencies than BJTs.
JFETs require less input power to operate.
