Yes i meant voltage would be applied to the gate allowing current to go from drain to source.
Thanks for your recap but still i can't what you said with the graph i posted:
A depletion mode FET conducts when Vgs = 0V, and requires a gate voltage to reduce the drain current.
Then why the 5V VGS curve is above the 0V one on the graph?
Depletion mode MOSFETs a specialty, hard to source likely to go obsolete. All JFETs are depletion mode.
I guess there's an alternative then, what is it?
Thanks again
