| representation of a sinusoidal integral quantity by a complex quantity whose argument is equal to the initial phase and whose modulus is equal to the RMS value
Note 1 to entry: For a quantity the phasor is , where is the RMS value and is the initial phase. A phasor can also be represented graphically.
Note 2 to entry: Electric current phasor and voltage phasor are often used.
Note 3 to entry: The similar representation with the modulus equal to the amplitude is sometimes also called "phasor".
