How does the threshold voltage affect the operation of a MOSFET?.
- A.It determines the maximum current flow
- B.It defines the minimum gate voltage required to turn the MOSFET on
- C.It indicates the power rating of the MOSFET
- D.It has no effect on the MOSFET operation
Model answer
What a good answer should say
- It defines the minimum gate voltage required to turn the MOSFET on
Explanation
Why this works
The threshold voltage is the minimum gate-to-source voltage that must be applied to the MOSFET for it to conduct current between the source and drain, thus determining its operational state.
