(nonâ³linâ²Ä-Är) Not linear; not obeying a linear relationship. In mathematics, a linear equation may be given in the form y = mx + b, where x is the independent variable, and y is the dependent variable. A nonlinear relationship cannot be represented by such an equation.
In an electric circuit, a nonlinear element or nonlinear device is an electrical element which does not have a linear relationship between current and voltage. A diode is a simple example. I = I 0 e V / V T {\displaystyle I=I_{0}e^{V/V_{T}}}.
