Drain Resistance in Transistor Amplifiers Formulas

Drain resistance is the ratio of change in drain to source voltage to corresponding change in drain current for a constant gate to source voltage. And is denoted by R_d. Drain Resistance is usually measured using the Kilohm for Electric Resistance. Note that the value of Drain Resistance is always positive.
