(2023-11-18 "A phasor is a tool in mathematics. It is used to show numbers in a different coordinate system. Certain electronic component s have models that can be described more easily by the use of phasors.
Inductors add a +90º "phase", while
capacitors add -90º "phase". Both elements work on the imaginary axis.
Resistors have 0º "phase", and are considered real.")

portmanteau of phase + vector. 위상,phase 벡터,vector ... 위상벡터,phase_vector ?
