When drain voltage equals the pinch-off-voltage, then drain current ___________ with the increase in drain voltage?

Correct answer: C. remains constant

  • A. decreases
  • B. increases
  • C. remains constant
  • D. none of the above

Explanation

At pinch-off, the JFET enters its saturation or constant-current region, where further increases in drain voltage produce nearly no increase in drain current. The current is then mainly controlled by the gate-source voltage.
