Reactance (in ohms) = 1/(2 pi * capacitance * frequency).
Capacitance is in farads. Frequency is in Hertz (cycles/second).
So increasing capacitance or increasing frequency will decrease reactance.
capacitive reactance is inversely proportional to the capacitance of the capacitor and frequency of the AC line reactance (in ohms) = 1/(capacitance * frequency)
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
in a series lcr ckt., wen d voltage across inductor Vl is > dan voltage across capacitor Vc, d voltage leads the current by an angle phi... n wen Vc > Vl d current leads the voltage by an angle phi... resonance occurs wen d reactance of inductor Xl = reactance offered by capacitor Xc... n hence at resonance, current through the circuit is max n reactence of ckt is minimum...
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance

The capacitive reactance of a capacitor increases as the frequency decreases.
for inductor, reactance XL = 2*pi* f *L, if frequency doubles then reactance increase. But for capacitor, reactance Xc = 1/(2*pi*f*C). In this case if frequency doubles the reactance decrease.
A capacitor will oppose the flow of a.c. due to its capacitive reactance (Xc), expressed in ohms.The capacitive reactance for a given capacitor is inversely-proportional to the frequency of the supply; in other words, the higher the frequency, to lower the capacitive reactance.
Because reactance of capacitor is inversly proportional to the frequency i.e- Xc=1/(2*pie*f*c) where f is frequency and c is capacitance of capacitor.
The capacitive reactance of a 1 µF capacitor at a frequency of 60 Hz is about 2700 ohms.
It is the capacitive reactance of a capacitor that causes it to oppose the passage of a.c. current. Since capacitive reactance is inversely-proportional to frequency, the lower the frequency, the greater its reactance, and the more it will oppose the flow of a.c.
Current Flow I believe.
inverse of frequencyAnswerReactance is inversely-proportional to frequency of the supply, and the capacitance of the capacitor.
Capacitors have an equivalent reactance of 1/jwC (ohms) where w is the angular frequency of the AC signal and C is the capacitance. As the frequency of the signal across the capacitor increases, the capacitor reactance approaches 0 (capacitor acts like a short circuit). As the frequency of the signal across the capacitor decreases, the capacitor reactance approaches infinity (capacitor acts like an open circuit). So, if you have a high frequency signal (like a step input) the capacitor will momentarily act like a short.
reactance due to the capacitance of a capacitor or circuit,equal to the inverse of the product of the capacitance and the angular frequency.
