When output characteristics (Ids versus Vds) plotted for n-channel JFET at Vgs is positive with respect to source, What will be expected at the output current?

 

good question. i just consulted 4 texts, and not one plotted anything above Vgs = 0v, implying max drain current was achieved. theoretically applying positive bias at the gate would attract addditional current carriers to the region, but also cause an attraction of those same carriers to the gate thereby disturbing current flow through to the drain.

Actually what happens...to my view...when the voltmeter or digital multimeter reads the value of Vgs...those values comes under the negative only...There is no question of taking values of
Vgs positive... U can clarify this doubt...with some others also..

 

Hello,

A lot of information on Jfet's can be found in the links of this page:
