A voltage-variable resistor employing feedback-linearized photoconductors

Creator:

Johansen, Donald Grover

Abstract:

A rheostat is an adjustable resistor so constructed that its resistance may be changed without opening the circuit in which it may be connected. Conventional rheostats are adjusted mechanically. This thesis presents a method of adjusting resistance electrically by varying the light intensity incident on the surface of a photoconductive...
