The paper presents researches of dependence of stabilization current from the external resistance connecting the source and the gate of the field-effect transistor in the mode of the current limiter — a two-pole terminal. At the assumption of quadratic dependence of a current from blocking voltage, experimental curves agree well with the calculation data. The established interrelation between a current of stabilization and external resistance is of interest by working out of sources and current terminators.
