Linear (Straight) circuit:
An electronic circuit where the info sinusoidal flood of recurrence f give a stead state yield. This circuit take after ohms law and the estimation of electronic parts doesn't change with the level of voltage of current in the circuit.
Non-Linear (Non direct) circuit:
The circuit in which the parameters change as for current and voltage. The parameter esteem like resistance, capacitance, inductance, waveform, recurrence and so on, is not consistent. This circuit doesn't take after ohms law and the v-i attributes are not a straight line.
A nonlinear component is one in which the current is not proportional to the voltage, in other words it does not follow Ohm's law. The commonest nonlinear component is a diode. A nonlinear circuit is one with a nonlinear component in it.
The amplifier is supposed to be an electronic circuit. Electronic circuits are nonlinear circuits, which may be modeled in the time domain by means of nonlinear differential equations and nonlinear algebraic equations. The kernel of the solution of the nonlinear equations is the solution of a linear equation system i.e. the nonlinear components and couplings are approximated with linear relations valid for small signals. Iterations are performed until the laws of Kirchhoff are fulfilled. The instant set of linear equations is the small signal model for the amplifier. If the amplifier is excited with a dc power source it assumes an active state called the bias point or quiescent point. If the relation between the input and the output signals of the amplifier is measured to be (almost) linear in the bias point then we assume a small signal amplifier with time independent bias point else we assume a large signal amplifier.
Nonlinear lines do not exist since a line, by definition, must be linear.
Linear systems are easier to understand and help you build an understanding of the workings of a system. Once you have a firm understanding of linear systems and the mathematics are understood you will be in a better position to understand more complex non-linear systems.
A load line is used in graphical analysis of nonlinear electronic circuits, representing the constraint other parts of the circuit place on a non-linear device, like a diode or transistor. It is usually drawn on a graph of the current vs the voltage in the nonlinear device, called the device's characteristic curve. A load line, usually a straight line, represents the response of a linear circuit connected to the nonlinear device in question. The operating point(s) of the circuit are the points where the characteristic curve and the load line intersect; at these points the current and voltage parameters of both parts of the circuit match
No, superposition theorem can only be applied to linear circuits. Nonlinear circuits do not obey the principle of superposition because the relationship between current and voltage is not linear.

A nonlinear component is one in which the current is not proportional to the voltage, in other words it does not follow Ohm's law. The commonest nonlinear component is a diode. A nonlinear circuit is one with a nonlinear component in it.
Nonlinear devices are components that do not follow a linear relationship between input and output. This means that their response is not proportional to the input signal. Examples include diodes, transistors, and nonlinear capacitors. Nonlinear devices are often used in electronic circuits to perform functions like signal processing and modulation.
since the diode shows its characteristics in a non linearly it is called as nonlinear element since the transistor shows its characteristics in a linear way it s called as linear element Transistors are typically operated in their linear region (such as when used in amplifier circuits), or as switches (where you will in general ignore the nonlinearity of the transistor). Transistors are typically DC biased to operate in this linear region. Diodes are not biased in this way. Strictly speaking, both are nonlinear devices, although transistors can be used in their linear operation region, while diodes are not.

Yes, the rate of change can be linear or non-linear.
This is non-linear
It is linear.
