Q. Give the Shockley's equation for the transfer characteristics of JFET's?

844_Transfer characteristics of JFETs.png

Where ID is the drain current and VGS is the voltage across gate and source. The squared term of the equation will result in a non linear relation between ID and VGS producing a curve that grows exponentially with decreasing magnitudes of VGS. the transfer characteristics defined by shockley's equation are unaffected by the network in which the device is employed.
