Abstract
Voltage and current of electricity are presented by complex functions. Since product of voltage and current represents power, power is presented by complex function. Real part of power presents energy, and imaginary part of power presents reactive power. Eigen oscillation is caused by reactive power. LC ladder circuit has eigen oscillations. This paper shows that a circuit obtained by a parallel connection of two LC ladder circuits also has eigen oscillations.
