At a frequency of 1kHz: Again at a frequency of 20kHz: where: ƒ = frequency in Hertz and C= capacitance in Farads Therefore, it can be seen from above that as the frequency applied across the 220nF. . At which frequency would a 2.2uF Capacitor have a reactance value of 200Ωs? Or we can find the value of the capacitor in Farads by knowing the applied frequency and its. . What will be the value of a capacitor in farads when it has a capacitive reactance of 200Ω and is connected to a 50Hz supply. We can see from the above examples that a capacitor. . So, we can summarize the behaviour of a capacitor in a variable frequency circuit as being a sort of frequency controlled resistor that has a high capacitive reactance value (open circuit condition) at very low frequencies and. . We remember from our tutorial about Resistors in Series that different voltages can appear across each resistor depending upon the value of the resistance and that a. The capacitor reacts very differently at the two different frequencies, and in exactly the opposite way an inductor reacts. At the higher frequency, its reactance is small and the current is large.

Capacitive reactance is a complex number with a phase angle of -90 degrees. I hope this helps! The two factors that determine the capacitive reactance of a capacitor are: Frequency (f): The higher the frequency of the AC signal, the lower the capacitive reactance.
This is the capacitive reactance calculator – a great tool that helps you estimate the so-called resistance of a capacitor in an electric circuit. You can find the capacitive reactance formula in the text below, and we explain why the reactance occurs for alternating current but not direct current.
When dealing with AC capacitance, we can also define capacitive reactance in terms of radians, where Omega, ω equals 2πƒ. From the above formula we can see that the value of capacitive reactance and therefore its overall impedance ( in Ohms ) decreases towards zero as the frequency increases acting like a short circuit.
At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723.3KΩ (giving the effect of an open circuit). At very high frequencies such as 1Mhz the capacitor has a low capacitive reactance value of just 0.72Ω (giving the effect of a short circuit).
As frequency increases, capacitive reactance decreases. This behaviour of capacitor is very useful to build filters to attenuate certain frequencies of signal. Capacitive reactance is also inversely proportional to capacitance. Capacitance and capacitive reactance both changes when multiple capacitors are introduced to the existing circuit.
Reactance changes with respect to frequency of voltage and current. Unlike resistance, reactance does not dissipate heat when it opposes the current. It opposes the current in different way. A capacitor has both resistance and reactance, therefore requiring complex numbers to denote their values.
