AI Customer ServiceThe Impedance of a capacitor (Capacitive reactance) is the measure of the opposition to a change of the electrical current in this component. It can be summarized, in a very general way, that a capacitor lets the high frequencies signals pass and blocks the low frequencies signals. (including 0 Hz signals)
Low Frequency (f 1/ (2πC)): The capacitive reactance increases dramatically at very low frequencies and eventually reaches infinity. As a result, very little current may pass through the capacitor, making it behave like an open circuit. In other words, the capacitor has a very high impedance.
The impedance of a capacitor decrease with increasing frequency as shown below by the impedance formula for a capacitor. At low frequencies, the capacitor has a high impedance and its acts similar to an open circuit. In high frequencies, the impedance of the capacitor decrease and it acts similar to a close circuit and current will flow through it.
Here are the primary types of capacitor impedance encountered in electrical circuits: Capacitive Reactance (Xc): Capacitive reactance is a type of impedance that arises in capacitors when subjected to an AC signal.
Impedance Magnitude: The magnitude of capacitor impedance represents the overall opposition to the flow of AC current offered by the capacitor. It is the absolute value of capacitive reactance and is calculated using the same formula as capacitive reactance: |Zc| = |Xc| = 1 / (2πfC)
Reactance is expressed as an ordinary number with the unit ohms, whereas the impedance of a capacitor is the reactance multiplied by -j, i.e., Z = -jX. The -j term accounts for the 90-degree phase shift between voltage and current that occurs in a purely capacitive circuit. The above equation gives you the reactance of a capacitor.
