A capacitor alone doesn't have a frequency. The combination
of a capacitor and an inductor (coil) has.
-- Read the value of capacitance printed on the capacitor, or measure it. Call it ' C '.
-- Read the value of inductance printed on the coil, or measure it. Call it ' L '.
The resonant frequency of the combination of those two components is
F = 1 / (2 pi) sqrt(L C)
The two factors that determine the capacitive reactance of a capacitor are the frequency of the AC voltage applied to the capacitor and the capacitance value of the capacitor. At higher frequencies and with larger capacitance values, the capacitive reactance decreases.
The two factors that determine the capacitive reactance of a capacitor are the frequency of the alternating current passing through the capacitor and the capacitance value of the capacitor. Capacitive reactance (Xc) is inversely proportional to the frequency (f) and directly proportional to the capacitance (C), as calculated using the formula Xc = 1 / (2πfC).
To determine the charge on a capacitor, you can use the formula Q CV, where Q is the charge, C is the capacitance of the capacitor, and V is the voltage across the capacitor. By measuring the capacitance and voltage, you can calculate the charge on the capacitor using this formula.
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.
When frequency increases, the energy of the radiation increases. Additionally, the pitch of sound also increases with frequency. In electrical circuits, the impedance of a capacitor or inductor also increases with frequency.

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 cutoff frequency of filter depends upon the value of capacitor and resistance. Therefore, below cutoff frequency or above this frequency, capacitor allow to pass all other frequencies.

Sure, but it won't mean anything unless the Thevenin source is an AC source. In that case, simply determine the frequency of the source, and draw the appropriate reactance in the circuit where the capacitor belongs. If the Thevenin source is DC, then the frequency is zero, the reactance of the capacitor is infinite, and you can show it as an open circuit, i.e. not there.
To determine if a capacitor is defective, use an Ohmmeter of a Multimeter.
A capacitor totally blocks DC current (it's an open circuit to it). The higher the frequency, the less resistance (impedance) the capacitor has.
A capacitor is required in electronics when we are charging and frequency circuits.
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.
The capacitive reactance of a capacitor increases as the frequency decreases.
yes, capacitive reactance is inversely proportional to frequency.
