phasor
thumb|An example of series RLC circuit and respective phasor diagram for a specific . The arrows in the upper diagram are phasors, drawn in a phasor diagram ([[complex plane without axis shown), which must not be confused with the arrows in the lower diagram, which are the reference polarity for the voltages and the reference direction for the current.]]
