If the current does not change linearly with the change in applied voltage then it is called as
Right Answer is:
Non-linear circuit: The circuit whose parameters change with the application of voltage or current is called a non-linear circuit.
A non-linear circuit element is one in which the current does not change linearly with the change in applied voltage. A semiconductor diode operating in the curved region of characteristics as shown in Fig. 1.28 is common example of non-linear element. Other examples of non-linear elements are voltage- dependent resistor (VDR), voltage-dependent capacitor (varactor), temperature-dependent resistor (thermistor), light- dependent resistor (LDR), etc. Linear elements obey Ohm’s law whereas non-linear elements do not obey Ohm’s law.
