HOW TO CALCULATE                                                                                   TABLE OF  CONTENTS



             THE DRAIN CURRENT











                                                                                                                    CHAPTER 4








                                                                VGS                 2

                        ID = IDSS    1-

                                                          VGS (OFF)







                          ID = drain current

                          IDSS = maximum saturation drain current                                                   CHAPTER 3


                          VGS(off)= -VP ; pinch-off voltage







                VGS(off) will always have the same magnitude value as VP.
                                                                                                                    CHAPTER 2

                For example:


                                       If VP = 6V; then VGS(off) = -6V
