Determine the forward transconductance of a JFET biased at Vgs = - 2V.......?

Question

ok the question is Determine the forward transconductance of a JFET biased at Vgs = -2V. From the datasheet, Vgs(off) = -7V and gm = 2000microS at Vgs= 0V. Also determine the forward tranfer conductance, gfs.

i do NOT understand what to do at all

Answer 1

You keep asking these questions. don't you think it would help to provide the part number so we can look up the data sheet?
