Question

id becomes zero at the pinch-off voltage
select one:
○ true
○ false

Explanation:

In field - effect transistors, the drain current (\(I_D\)) does not become zero at the pinch - off voltage. At pinch - off, the drain current reaches a saturation value (remains relatively constant for further increase in drain - source voltage), and \(I_D\) becomes zero at the cutoff voltage (when the gate - source voltage is below the threshold voltage for enhancement mode or at a certain negative voltage for depletion mode, which is different from pinch - off voltage). So the statement is false.

Answer:

False
