In quantummechanics it helps reduce the amount of calculating to be done.Originally posted by sonhouseTHAT I know: Complex numbers are inherently involved with alternating current and RF, you have to use complex #'s to solve problems in current flow and voltages, say on an RF open wire feedline for instance, the current sine wave and the voltage sin waves are not in sync and require complex #'s to solve the real energy exchange, absorption or emission of RF ...[text shortened]... ameters into Mathcad or other software pacs and don't have to do the math by hand any more.

Complex exponents are way easier to deal with than a bunch of sines and cosines.
