Definition: | 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 root-mean-square value (103-02-03) Note 1 to entry: For a quantity $a(t)=A\sqrt{2}\mathrm{cos}\text{\hspace{0.17em}}(\omega \text{\hspace{0.17em}}t+{\vartheta}_{0})$ the phasor is $A\text{\hspace{0.17em}}\mathrm{exp}\text{\hspace{0.17em}}j{\vartheta}_{0}$. Electric current phasor $\underset{\_}{I}$ and voltage phasor $\underset{\_}{U}$ are often used. Note 2 to entry: The similar representation with the modulus equal to the amplitude is sometimes also called "phasor". See 103-07-14. Note 3 to entry: A phasor can also be represented graphically. | ||
