|delta Id/delta Vi = Gm
Gm=tranconductance=1.5 milli Siemens

|dI/dV = gm(transconductance).
>dI = gm*dv.
>dI = 1.5m*2;.
>dI = 3mA.

|Id = 2 sqrt(gm*Vgs).
gm = 1.5x10^-3.
Vgs = 2.
So Id = 3mA.

|What is the input delta, what is the drain current delta?|
|Shadan said: (Nov 24, 2017)|
|Transconductance(gm)= Del( ID) /Del( VGS)
and also Transconductance is reciprocal of resistance so we no that Resistance =V/I.
Then you will found 3mA.
