Abstract :
From the energy point of view, this paper presents a general formula for the calculation of capacitance, which is not only suitable for Coulomb electric fields but also for induction electric fields. Based on this point, it discusses how the mechanism of turn-to-turn capacitances in the inductive electric field is the existence of inductive electric field and electric field energy, which are generated by the time-varying magnetic field. The turn-to-turn capacitance is proportional to the length of one turn and related to the physical properties of the dielectric. In the Coulomb electric field, the electrostatic capacitances between turns are zero.
