When the controlling voltage of an n-channel JFET
is kept at 0 V, and a voltage greater than the pinch-off voltage is applied between the drain and the source terminal, the JFET:
a)Gets into the cut-off region
b)Has a constant output voltage
c)Acts as a variable resistor
d)skipped Acts as a current source
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
When the controlling voltage of an n-channel JFET ... moreis kept at 0...
The transfer characteristics for an n-channel JFET when the controlling voltage, VGS = 0V  is shown below.

It can be seen from the characteristics that when the voltage between the drain and source (VDS) becomes greater than the pinch-off voltage (VP), the drain current remains essentially the same, as the region between the two depletion regions will increase in length. The drain current ID is fixed at the value ID = IDSS, where IDSS is the maximum drain current.
Hence, the JFET acts as a current source as shown below, for VGS = 0V, VDS>Vp
