Current Noise and Nonlinearity in Carbon Resistors

The relationship between nonlinearity and current noise in carbon resistors is investigated. Results are given for seven different groups of resistors, and they show that there is a correlation between the nonlinearity of a resistor and its current noise: in general, noisy resistors are more nonlinear than quiet ones. The character of the relationship varies considerably among the types tested, and it depends on the construction of the resistor.
