Question 1.
What happens in the Ohmic region of a JFET?
Show hintHide hint
Think about how it reacts to voltage.
Question 2.
What is the drain current in the Cut-off region?
Show hintHide hint
What happens to the channel here?
3Question 3.
What characterizes the Ohmic region of a JFET?
- The JFET behaves like a diode.
- The JFET behaves like a resistor.
- The current is zero.
Show hintHide hint
Relate to how resistance behaves.
4Question 4.
In which region does the JFET operate as an amplifier?
- True
- False
Show hintHide hint
Consider the application in amplification.
Question 5.
A JFET is used in an audio amplifier circuit. Describe how you would bias it to operate in the Active region.
Show hintHide hint
Consider the requirements for maintaining output levels.
Question 6.
Explain the implications of incorrect biasing in the JFET, leading to it remaining in the Cut-off region.
Show hintHide hint
Think about the consequences when a device does not pass current.
