Asymmetrical waves, such as a sinusoidal voltage or current waveform, have a positive half cycle that equals the negative half cycle. This means that after completing a full cycle, the mean result is equal to zero. counterfeit versionWebReactance 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. counterfeit vocabulary
