Imaginary numbers in alternating current

Witrynanumbers. In the context of alternating current theory, the imaginary unit is customarily given the symbol j rather than i, so that the symbol i is available, if need be, for electric currents. I am making the assumption that the reader is familiar with the basics of complex numbers; without that Witryna10 lip 2024 · J in electrical mathematics (or i, for imaginary in ordinary mathematics) just happens to follow the same progression as the voltage vector when ac current is passed through a reactance. So the real number and +-J represent the sides of the impedance triangle formed by the voltages across a resistor and an inductor or capacitor.
