Drain characteristics: It gives the relation between drain current and drain to source voltage at a constant gate to source voltage.

Ohmic region: From O to A, in the ohmic region, drain current is directly proportional to drain to source voltage.

Saturation or pinch off region: From A to B, drain current increases slowly with increase in drain to source voltage. The curve from B to C is the saturation region in which the drain current remains a constant.

Curve from C to D is the breakdown region. In this region, drain current increases rapidly with the increase in drain to source voltage.

Transfer characteristics: It gives the relation between drain current and gate to source voltage for a constant drain to source voltage. Keeping VDS constant, VGS is varied and corresponding ID are nated. The graph obtained is shown:
