What is Linear and nonlinear elements of a network?

Answer 1

Linear elements :

In an electric circuit, a linear element is an electrical element with a linear relationship between current andvoltage. Resistors are the most common example of a linear element; other examples include capacitors,inductors, and Transformers.

Nonlinear Elements :

A nonlinear element is one which does not have a linear input/output relation. In a diode, for example, the current is a non-linear function of the voltage.Most semiconductor devices have non-linear characteristics.
