在《变压器》的教学中,教师都会从变压器的理想化过程中得到原副线圈电压、功率、电流、频率的关系.为了进一步增强学生感性认识,笔者总结了一些变压器频率关系实验,希望能给大家提供帮助.1听频率关系 In the teaching of “Transformer”, teachers get the relationship of the voltage, power, current and frequency of the primary coil from the idealization of the transformer.In order to further enhance the perceptual knowledge of the students, the author summarizes some experiments on the relationship between transformers frequency in the hope of giving Everyone to help .1 listen to the frequency relationship
