Exam-style question
Try this first
Explain how the gate voltage affects the operation of a MOSFET.
Model answer
What a good answer should say
- The gate voltage controls the conductivity of the MOSFET.
- When the gate voltage exceeds a certain threshold, it creates an electric field that allows current to flow between the drain and source.
- If the gate voltage is below the threshold, the MOSFET remains off, preventing current flow.
Explanation
Why this works
This question assesses the understanding of MOSFET switching behavior, specifically how gate voltage influences operation. A strong answer demonstrates knowledge of the relationship between gate voltage and current flow.
