WebReactance 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. WebIn direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction. Most of the digital electronics that you build will use DC.
