Is the capaci... Is the capacitor linear or nonlinear? A linear electrical element is an ideal capacitor. The flow of current is proportional to the voltage applied. Because of their scaling feature, capacitors are linear elements. Hence, capacitors are linear.
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).
... concept of the Modular Active Capacitor is based on non-linear capacitors. When a capacitor is characterized by a straight line through the origin of the V-Q plane, it is called a linear capacitor.
The same capacitor containing no dielectric, charged to a voltage of 72 volt is connected in parallel to the first non-linear uncharged capacitor. The final voltage across the capacitor is?
even if the capacitances are nonlinear. Unfortunately, the familiar formulas for stored charge and energy are not universally valid and hold true only for the special case of constant capacitances. The more fundamental relations define capacitance as the rate of change of charge with respect to voltage, and voltage itself is the meas
by the way, if you look at this in the purely DC static case: no matter what constant voltage you apply to a capacitor, after everything has settled, the current going through the cap is 0; N times 0 is still zero, so linearity isn't really broken in any case. +1 for the last line.
