Are capacitors and inductors linear?
Yes, capacitors and inductors are linear. A component is said to be linear if the current is directly proportional to the voltage over its entire working range. The reactance of the capacitor and inductor is fixed for a given frequency. I f the voltage is increased, the current flowing through the circuit also increases.

As it turns out, you can construct these by combining resistors with capacitors or inductors: a resistor in parallel with an inductor gives you an I-I'' relationship, and a resistor in series with a capacitor gives you a V-V'' relationship.

6 FAQs about [Capacitor linear relationship capacitor]
Why is a capacitor a linear component?
A capacitor is a linear component because voltage and current as functions of time depend in a linear way on each other. In the context of relations of two functions (of time) to each other (and not just values at one instance of time) linearity means that the principle of superposition holds (as Neil_UK has pointed out).
What is the slope of a capacitor line?
The slope of the capacitor line is $\text C$. Likewise, the inductor law can be graphed as a straight line with $di/dt$ as the horizontal axis and $v$ as the vertical axis. The slope of the inductor line is $\text L$. This means ideal capacitors and inductors are also linear elements. Now we have three linear circuit elements: $\text {R L C}$.
How do you describe a capacitor?
As you said, one way to describe a capacitor is V = Q / C. This says that the voltage on a capacitor is proportional to the charge it is holding, and that proportionality constant is the inverse of the capacitance. In the parlance of a linear equation as above, V = f (Q). Since f (Q) = Q/C, it should be clear that this equation is linear because:
Why is a capacitor a fundamental element?
In both digital and analog electronic circuits a capacitor is a fundamental element. It enables the filtering of signals and it provides a fundamental memory element. The capacitor is an element that stores energy in an electric field. The circuit symbol and associated electrical variables for the capacitor is shown on Figure 1. Figure 1.
Which capacitor is a constant capacitance?

What is a capacitor insulator?
A capacitor is a circuit component that consists of two conductive plate separated by an insulator (or dielectric).
