At cut-off, the JFET channel is _____________?
Correct answer: B. completely closed by the depletion region
- A. at its widest point
- B. completely closed by the depletion region
- C. extremely narrow
- D. reverse baised
Explanation
At cutoff, the reverse-biased gate junction's depletion regions extend across the channel and stop majority-carrier flow. Therefore, the channel is effectively completely closed by the depletion region.
