HIGH VALUE RESISTORS: STUDY OF THEIR BEHAVIOUR VERSUS APPLIED VOLTAGE

F. Galliana, G. Boella

Abstract

Experimental results concerning the behaviour of some high value resistors versus applied dc voltage are given. The measurements have been carried out at IEN on typical standard resistors, normally available in National and secondary laboratories, in the field 10 MΩ ÷ 1 TΩ by means of the measurement systems described in [1, 2]. The measurement results, with which we tried to determine the voltage coefficients, showed for most of the measured resistors a behaviour versus voltage that is the addition of linear and quadratic components.
