Every analog circuits usually consists of voltage or current sources, some resistors, transistors etc. Coming to the transistor, they constitute non-linear part of the circuits. They behave ...

Components which show I–V graphs that are not straight lines are non-linear circuit elements. The current through them is not directly proportional to the potential difference across them.
