| 摘 要： | 应用电磁学定律讨论了交流电路的元件-电阻、电感和电容中的能量的情况.指出了电阻能量的消耗来自于电阻外的电磁场,电磁能量的传输与电阻外的能流密度 S有关,电感和电容都不消耗能量,只与外界进行电磁能量的交换,并且与电磁能量的传输无关.从而对交流电路的电磁能量的传输和转化作了比较详细的描述.

| Abstract: | In this article,the energy problem of alternating circuit components,including resistor?inductor and capacitor,are discussed by using the electromagnetic law.We point out that the dissipation of energy in resistance comes from electromagnetic field outside the resistor,the transmission of electromagnetic energy is caused by energy flux density outside resistor,while the inductor and capacitor dissipate not energy but exchange energy with external environment and have no relation to the transmission of electromagnetic energy.The transmission and transformation of electromagnetic energy in alternating circuit are described in detail. |
