Small capacitor markings are as follows:
Xc = 1/(2 fC)
C is expressed in Farads, f in Hertz and Xc in ohms
For a 10 microfarad capacitor at 1000 Hertz reactance is 15.92 ohms and at 500 Hz 31.85
A 0.1 microfarad capacitor at 1000Hz = 1592.36 ohms and 3184.71 ohms.
10 microfarad at 60 Hz is 265.4 ohms, 1 microfarad is 2653.9 ohms and 0.1 is 26539 ohms.
As frequency goes up reactance goes down, and the smaller the capacitor the more reactance for a given frequency.
