All the relationships for capacitors and inductors exhibit duality, which means that the capacitor relations are mirror images of the inductor relations. Examples of duality are apparent in Table
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
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.
Description. The Variable Capacitor block represents a linear time-varying capacitor. The block provides two options for the relationship between the current i through the capacitor and the voltage v across the device when the capacitance at port C is C.The Equation parameter determines which of the following equations the block uses:
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. So we''ve covered every possible linear relationship up to first order with just the three elements.
The slope of the inductor line is text L L. This means ideal capacitors and inductors are also linear elements. Now we have three linear circuit elements: text {R L C} R L C. With just these
Mathematically this can be expressed as πΆπΆ= ππ/ππ or alternately, ππ= πΆπΆ. Since most capacitors ππ at steady -state are maintaining an amount of charge that is nowhere near the limit of the material, the capacitor has a linear relationship between the total number of

I''m trying to use an LM1117 linear voltage regulator to convert to 3.3v (input voltage will be 9 or 5 volts; not yet decided). The datasheet suggests using 10uF tantalum capacitors on the input and output.

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).
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: $\text {R L C}$.
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:
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.

A capacitor is a circuit component that consists of two conductive plate separated by an insulator (or dielectric). Capacitors store charge and the amount of charge stored on the capacitor is directly proportional to the voltage across the capacitor.
