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.

• Polar form:
• Cartesian or rectangular form:
