An n-channel JFET has the following parameters: I_{DSS} = 10 mA and V_{p} = -3.5 V_{p} . What will be the value of the drain current I_{D} when V_{Gs} = -2.5 V?
I_{D}=I_{DSS}\left[1-\frac{V_{GS}}{V_{p}} \right] ^{2}
=10\left[1-\frac{-2.5}{-3.5} \right] ^{2}
=10\left[1-0.714 \right] ^{2}
= 0.8 18 mA
