对圆形平行板电容器电磁能量转换问题的浅析

The preliminary analysis of electromagnetic energy transition of the circular parallel-plate capacitor

圆形平行板电容器当接通交变电流时 ,板内外会产生磁场 ,并伴随着电磁波辐射 ;辐射出去的电磁能等于电容器减少的储能。

When the circular parallel-plate capacitor is connected to an alternating current,the magnetic field will appear both inside and outside the plates with the electromagnetic wave radiating. The radiated electromagnetic energy is equal to the reserved energy which the capacitor lost.
