WebMar 18, 2012 · Complex numbers are used in electrical engineering for quantities that have a magnitude and a phase. Electrical impedance is the ratio of current to voltage. For AC currents and voltages, the current and voltage waveforms might not be in phase; the phase of the impedance tells you this phase difference. Share.

WebJan 23, 2013 · Complex numbers are used in electrical engineering all the time, because Fourier transforms are used in understanding oscillations that occur both in alternating … WebComplex numbers are used in RF engineering for impedances, which is just a fancy resistance. The thing is that a resistor is just a straight real number like 50 ohms, whereas an inductor and a capacitor also have resistance but its the sum of a real part and imaginary part. this imaginary part its called a reactance.
