1. Complex impedance

The function of a dielectric is to store and isolate "two electricities" . As this function is never perfect, the dielectric is generally represented by a complex impedance Z_ . This representation makes it possible to account for the phase shift of the voltage with respect to the current noted φ and its complement δ to arrive at the phase shift of a perfect dielectric: π/2 = δ-φ (figure 1...
