Electrical Reactance: What is it? (Inductive & Capacitive We generally denote it with English letter D. Therefore, From, the above expression of D, it is clear that electric field intensity and electric field density are in same phasor. Phasors are based on the concept of complex numbers: combinations of real and imaginary quantities. It is a superset of both resistance and reactance combined. In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.. Quantitatively, the impedance of a two-terminal circuit element is the ratio of the complex representation of the sinusoidal voltage between its terminals, to the complex representation of the current flowing through it. Impedance (Z) of a series R-L circuit may be calculated, given the resistance (R) and the inductive reactance (XL).
