LC振荡电路的物理模型满足下列条件:①整个电路的电阻R=0(包括线圈、导线),从能量角度看没有其它形式的能向内能转化,即热损耗为零。②电感线圈L集中了全部电路的电感,电容器C集中了全部电路的电容,无潜布电容存在。③LC振荡电路在发生电磁振荡时不向外界空间辐射电磁波,是严格意义上的闭合电路。LC电路内部只发生线圈磁场能与电容器电场能之间的相互转化,即便是电容器内产生的变化
The physical model of the LC oscillator circuit satisfies the following conditions: 1 The resistance of the entire circuit R = 0 (including coils, conductors), and there is no other form of energy conversion from the energy point of inward, ie, the heat loss is zero. 2 Inductor coil L concentrates the inductance of all circuits. Capacitor C concentrates the capacitance of all circuits, and there is no non-draining capacitor. The 3LC oscillation circuit does not radiate electromagnetic waves to outside space when electromagnetic oscillations occur, and is a closed circuit in a strict sense. In the LC circuit, only the mutual transformation between the magnetic field energy of the coil and the electric energy of the capacitor occurs, even if the change occurs in the capacitor.
