Inductive Reactance
Reactance can be defined as opposition to the flow of alternating current inside passive components such as capacitor and inductor. Reactance is similar to resistance however resistance is not related to frequency of voltage or current in a circuit. Reactance changes with respect to frequency of voltage and current.
Capacitive Reactance
Capacitive reactance is how the impedance (or resistance) of a capacitor changes in regard to the frequency of the signal passing through it. Capacitors, unlike resistors, are …
How to Pick Audio Capacitors
because real-world capacitors do leak some DC, but not enough that we can‟t use the ideal model. The formula for reactance in ideal capacitors is: Reactance = 1 / (2 * pi * frequency in Hz * Capacitance) So a capacitor will have a greater reactance to low frequencies, and the larger the capacitor the lower the reactance.

AC Chapter 5: Capacitive Reactance and Impedance
AC capacitor circuits. Capacitors do not behave the same as resistors. Whereas resistors allow a flow of electrons through them directly proportional to the voltage drop, capacitors oppose changes in voltage by drawing or supplying current as they charge or discharge to the new voltage level. The flow of electrons "through" a capacitor is directly proportional …

How do capacitors work?
The two plates inside a capacitor are wired to two electrical connections on the outside called terminals, which are like thin metal legs you can hook into an electric circuit. Photo: Inside, an electrolytic capacitor is a bit like a Swiss roll. The "plates" are two very thin sheets of metal; the dielectric an oily plastic film in between them.
18.5 Capacitors and Dielectrics
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by

While ideal capacitors and inductors do not exhibit resistance, the voltage does react to the current. Unsurprisingly, we call this characteristic reactance and denote it with the letter (X). Reactance, like resistance, is a ratio of voltage to current. We define capacitive reactance as: [X_{C} = frac{v_c}{i_c} label{1.7} ]

Capacitive Reactance Calculator
The ''resistance'' to the current that can be passed by a capacitor is called the capacitive reactance. Although the reactance of a capacitor is different from the resistance of a resistor, but it is measured in Ohms just the same. Capacitive reactance is used instead of ordinary resistance in calculations using Ohm''s law.
Introduction to Capacitors, Capacitance and Charge
The parallel plate capacitor is the simplest form of capacitor. It can be constructed using two metal or metallised foil plates at a distance parallel to each other, with its capacitance value in Farads, being fixed by the surface area of the conductive plates and the distance of separation between them.

Understanding Impedance
Capacitors, or caps, store energy in an electric field between their plates. The impedance of a capacitor, known as capacitive reactance (XC), decreases with an increase in frequency. The formula for capacitive reactance is XC = 1/(2πfC), where C is the capacitance. Capacitors oppose changes in voltage, which gives them a unique role …

Capacitive reactance is the opposition that a capacitor offers to alternating current due to its phase-shifted storage and release of energy in its electric field.
