Reactance is symbolized by the capital letter "X" and is measured in ohms just like resistance (R). Capacitive reactance can be calculated using this formula: XC = 1/ (2πfC) Capacitive reactance decreases with increasing frequency. In other words, the higher the frequency, the less it opposes (the more it "conducts") AC current.
