理想变压器及其变压规律是交变电流部分一个最重要的内容.理想变压器本身不消耗能量,可以说,理想变压器本质上是一个理想的能量转输器,其输入功率等于输出功率.有关理想变压器的电压、电流等各种物理量的关系都是基于这种原理推导出来的.认清了理想变压器的本质后,我们就会发现 The ideal transformer and its transformation law is one of the most important parts of the alternating current part. The ideal transformer itself does not consume energy, it can be said that the ideal transformer is essentially an ideal energy transmitter, and its input power is equal to the output power. The relationship between transformer voltage, current, and other physical quantities is derived based on this principle. After recognizing the nature of the ideal transformer, we will find that
