equation 1 is time-domain equation 2 is phasor-domain (time-domain signals Fourier transformed into complex frequency space) You don't equate the two in the sense of setting both right sides equal. The two equations are equivalent forms of the same expression - just different representations of reality from two perspectives.

If not, under what conditions (1) and (2) can be applied? Thanks and regards, Jayaprakash. ===== Balachandran Jayaprakash Celestijnenlaan, 3/61, 3001, Heverlee, Leuven, Belgium.
