Angular notation or phasor notation is a notation used in electronics through the symbol ∠. In an abbreviation due to the frequent occurrence of the expression e and is used to describe phasors. Note that the angle φ is usually expressed in degrees. 1 e j & # x03D5; = 1 & # x2220; & # x03D5; & # xA0; {\displaystyle 1e^{j\phi }=1\angle \phi \!\ }
Where φ is the phase, and j is the imaginary unit (-1). You can move from a polar shape to a rectangular shape in the following way: A & # x2220; & # x03D5; = A cos & # x03D5; + j A without & # x03D5; {\displaystyle A\angle \phi =A\cos \phi +jA\sin \phi }
and vice versa (taking care to place the angle in the right quadrant): R + j X = R 2 + X 2 & # x2220; arctan ( X R ) {\displaystyle R+jX={\sqrt {R^{2}+X^{2}}}\angle {\arctan {({\frac {X}{R}})}}}
Where R is usually the resistive part of the impedance and X is usually the reactance.
