|with the decrease of Vgs,Id decreaseses.it is max. At 0 Vgs which is Idss|

|As with the decrease in the value of the Vgs the gate to channel junction become reversed biased which resist the flow of current.|

|Id = Idss(1-Vgs/Vp)2.
when Vgs = 0, Id = Idss :) :).

|When we plot drain characteristics of fet i.e btween Vds and Id when Vgs = 0v we get max value of Id at a point of voltage called pinch off voltage.|

|IDSS (referred to as the drain current for zero bias) is the maximum current that flows through a FET transistor, which is when the gate voltage, VG, supplied to the FET is 0V.|

|Id = Idss (1-(Vgs/Vp))2.
If Vgs = 0 then Id = Idss.
