Determining the reactance XC by Selecting a capacitor C and frequency f is the most suitable. Capacitive reactance (symbolic representation XC) is actually a way of measuring a capacitor's resistance to AC (alternating current).
Just like resistance it is calculated in ohms, however reactance is somewhat more complicated compared to resistance due to the fact its value is dependent upon the frequency (f) of the electrical signal entering the capacitor and also on the capacitance, C.
Capacitive reactance, XC = 1 / (2 × π × f × C)
where: XC = reactance in ohms (ohm), f = frequency in hertz (Hz), C = capacitance in farads (F)The reactance XC is substantial for low frequencies and smaller at higher frequencies.
For constant DC which can be zero frequency, XC is incalculable (complete opposition), as per the standard rule that says capacitors transfer AC but block DC.As an example a 1 µF capacitor carries a reactance of 3.2 kΩ for any 50 Hz signal, however once the frequency is bigger at about 10 kHz its reactance is reduced to just 16 Ω.
You may see the program but the function may not operate.
