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).
This technical column describes the basic facts about capacitors. This lesson describes the voltage characteristics of electrostatic capacitance. The phenomenon where the effective capacitance value of a capacitor changes according to the direct current (DC) or alternating current (AC) voltage is called the voltage characteristics.
Capacitor Characteristics Capacitors are often defined by their many characteristics. These characteristics ultimately determine a capacitors specific application, temperature, capacitance range, and voltage rating. The sheer number of capacitor characteristics are bewildering.
Capacitors are said to have good voltage characteristics when this variance width is small, or poor temperature characteristics when the variance width is large. When using capacitors in electronic equipment used for applications such as ripple rejection in power lines, the design must take into account the operating voltage conditions. 1.
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:
When it comes to importance, the nominal value of the Capacitance, C of a capacitor will always rank at the top of capacitor characteristics. This value can be measured in three ways: These values are printed directly onto the body of the capacitor in letters, numbers, and colored bands.
