高二《物理》“变压器”一节中叙述道“变压器工作时 ,输入的功率一部分从副线圈输出 ,另一部分消耗在发热上 .但是消耗的功率一般不超过百分之几 .”消耗功率便是有能量损耗 .那么 ,变压器工作时到底有哪些能量损耗 ?变压器工作时 ,除了发出嗡嗡的声音 ,损耗极少的能量外 ,还 In the “Transformer” section of “Physics” in the second year, it states that “When the transformer is in operation, part of the input power is output from the secondary coil, and the other part is consumed by heat. However, the power consumed does not exceed a few percent.” The power consumption is There is energy loss. Then, what are the energy losses when the transformer is working? When the transformer is working, besides the noise of the gongs and the little loss of energy,
