Exam-style question
Try this first
In a MOSFET, what happens to the drain current as the gate voltage increases beyond the threshold voltage?.
- A.The drain current decreases
- B.The drain current remains constant
- C.The drain current increases significantly
- D.The drain current becomes zero
Model answer
What a good answer should say
- The drain current increases significantly
Explanation
Why this works
As the gate voltage exceeds the threshold voltage, the MOSFET enters saturation, allowing a significant increase in drain current. This behavior is essential for applications where MOSFETs are used as switches or amplifiers, indicating their effectiveness in controlling larger currents.
