*The video claims to explain how to convert between complex numbers and phasors, but phasors ARE already complex numbers. The video is actually explaining how to transform complex numbers between cartesian and polar notation. Cartesian notation has the form a+jb, where $a$ is the real part, $b$ is the imaginary part, and $j$ is the imaginary constant (denoted $i$ in many other fields). Polar notation has the form $A*e^(j\theta)$, where $A$ is the magnitude and $\theta$ is the phase.

  • The video claims to explain how to convert between complex numbers and phasors, but phasors ARE already complex numbers. The video is actually explaining how to transform complex numbers between cartesian and polar notation. Cartesian notation has the form $ a+jb<\math>, where <math>a<\math> is the real part, <math>b<\math> is the imaginary part, and <math>j<\math> is the imaginary constant (denoted <math>i<\math> in many other fields). Polar notation has the form <math>A*e^(j\theta)<\math>, where <math>A<\math> is the magnitude and <math>\theta<\math> is the phase. **Answer to Comment 1 *Comment 2 **Answer to Comment 2 ---- [[2015 Spring ECE 201 Peleato|Back to 2015 Spring ECE 201 Peleato]] $
