Impedance of a capacitor – Capacitive reactance
The impedance – Capacitive reactance. Usually, capacitor are used in circuits with a frequency of signals different from zero (0 Hz). We can see, from the impedance formula in a capacitor, that the impedance is inversely proportional to the frequency. This means that if the frequency is zero (0 Hz) the impedance is infinite.

6 FAQs about [Impedance transformation of capacitor]
What is an equivalent impedance?
An equivalent impedance is an equivalent circuit of an electrical network of impedance elements [note 2] which presents the same impedance between all pairs of terminals [note 10] as did the given network. This article describes mathematical transformations between some passive, linear impedance networks commonly found in electronic circuits.
How do you calculate reactance & impedance of a capacitor?
The above equation gives you the reactance of a capacitor. To convert this to the impedance of a capacitor, simply use the formula Z = -jX. Reactance is a more straightforward value; it tells you how much resistance a capacitor will have at a certain frequency. Impedance, however, is needed for comprehensive AC circuit analysis.
What is a general impedance transform?
A general impedance transform for finding equivalent rational one-ports from a given instance of [Z] is due to Wilhelm Cauer. The group of real affine transformations is invariant in Z (s). That is, all the transformed networks are equivalents according to the definition given here.
How does a transformer change the impedance of a circuit?
A transformer also transforms the impedance of a circuit, since it changes the ratio of V/I. Using our rules above, the ratio of output impedance to input impedance is the square of the ratio of turns: So, if you use a transformer as a step-up transformer, it increases the voltage and the impedance at its output relative to its input.
What is the Tan L function in the impedance transformation equation?
Line For lossless lines, the tan l function in the impedance transformation equation tells us that the function is periodic and repeats. The function repeats every integer multiple of . 2 m Note: is the wavelength in the transmission line, not the free space wavelength 0.
Can a transformer be used to transform impedance levels?
This action is not available. Transformers and reactive elements considered in this section can be used to losslessly transform impedance levels. This is a basic aspect of network design. The ideal transformer shown in Figure 10.2.2 can be used to match a load to a source if the source and load impedances are resistances.
