A: capacitor behaves as a linear element as the current is independent of voltage across it. current (as o/p) varies as the time rate of change of voltage across it. so capacitor rarely shows appreciable non linearity, if it is operated in the specified voltage limit

∙ 8y agoIn this paper, the idea of implementing capacitors with DC/AC power converters (also called inverters) is proposed and demonstrated. Such capacitors are active capacitors. The voltage rating of an active capacitor is determined by the voltage rating of the power semiconductor devices used to build the inverter and the current rating of the capacitor is determined by the current rating of the power semiconductor devices used. The capacitance can be freely set in a very wide range and it is possible to have some special properties, e.g. to reduce harmonic current components.Active capacitors outperform passive capacitors in terms of tolerance, stability with respect to time and temperature.

∙ 8y agoA capacitor is used to store the static Electrical Energy between its two plates which are isolated from each other by means of a dielectric medium.
Now, it is found that, as we increase the applied voltage between two plates of the capacitor, the charge stored between two plates (by the virtue of the isolation between two plates) Also increases.
And It is the Applied Voltage (V) And Charge Stored between two plates of capacitors (Q) that are Linearly Related to each other.
So, we can say that the charge stored by the capacitor is linearly Dependent ( Directly Proportional ) to the Applied voltage Across it.
So. a capacitor is a linear device with respect to Charge - Voltage Relationship.
(And the same Relationship can be derived for Inductor , in which case, it is the Flux - Current Relationship that is Linear.)
And yes, For Capacitors And Inductors, The Conventional Voltage - Current (V-I) Relationships are not linear.
so, to Answer your Question,
Capacitor is a linear device BUT, for Charge - Voltage Relationship.
And Capacitor is a Non Linear Device For Voltage - Current Relationship.

What is a non linear line?
Nonlinear lines do not exist since a line, by definition, must be linear.
Why you study nonlinear systems when linear system is present?
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.
What is meant by non linear circuits?
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.
What do you mean by linearity in parameter and linearity in model?
Any model can be linear/nonlinear. Linearity can be in parameters or in variables. In Y=a+ b*x1 + c*x2 + d*x3 the model is linear in both parameters (b,c,d) and variables(x1,x2,x3) In Y=a+ (b+c)x1 + c*x2 + d*x3 the model is nonlinear in parameters (b,c,d) and linear in variables(x1,x2,x3) In Y=a+ bx1 + c*x2*x3 + d*x3 the model is linear in parameters (b,c,d) and nonlinear in variables(x1,x2,x3) In Y=a+ bx1 + c*x2*x3 + exp(b+d)*x3 the model is nonlinear in parameters (b,c,d) and nonlinear in variables(x1,x2,x3)
Differentiate between small signal and large signal amplifier?
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.

Is 3x plus 2 equals 0 linear or nonlinear?
It is linear.
Is y equals 9x3 - 8 linear or nonlinear?
This is non-linear
Is 6 linear or nonlinear?
6 is neither linear nor non-linear. It is just a number.
What does nonlinear and linear mean?
Linear means anything that forms a straight line. Nonlinear means the opposite. Something that doesn't form a straight line.
Examples of transcoding linear to nonlinear text?
Transcoding linear to nonlinear text is fairly straightforward. Nonlinear text usually refers to text with pictures. To transpose to linear text, simply remove the pictures and rewrite if necessary.
Is this equation linear or nonlinear Y equals -3x -2?
