Question

For a FET when will maximum current flows?

(a) Vgs = 0V

(b) Vgs = 0v and Vds >= |Vp|

(c) VDS >= |Vp|

(d) Vp = 0

The question was posed to me at a job interview.

The origin of the question is The Junction Field-Effect Transistor topic in division Field-Effect Transistors of Electronic Devices & Circuits

Answer 1

Right answer is (b) Vgs = 0v and Vds >= |Vp|

Easy explanation: For a FET the current reaches maximum that is IDSS occurs when Vgs = 0V and VDS >= |Vp|
