5.5 The Phasor Circuit cont.
Only currents and voltages are phasors (i.e., have time-function counterparts)
Don’t believe it? Then what’s Z(t) for the phasor circuit below if the phasors correspond to cosinusoids (so that Vs(t) = 10cos(3t) V. and i(t) » 1.49cos(3t - 63.43°) A.)?
Since Z = (3 + j6) W » 6.71/63.43° W, is Z(t) » 6.71cos(3t - 63.43°) W for example?!!
By KVL, I = Vs / Z = (10/0° V.) / (3 + j6)W » 1.49/-63.43°A.
N.B.: Where’s the differential equation?
