Phasor Representation
Phasor (phase vector) is a vector representing a sinusoidal function.
- Magnitude of the phasor: rms value of the wave
- Angle of the phasor: The angular position , with respect to a reference direction
Can also be represented by a complex number. But is used as the imaginary unit becasue is used for time-varying current.
