求翻译：变压器是变换交流电压、电流和阻抗的器件，当初级线圈中通有交流电流时，铁芯（或磁芯）中便产生交流磁通，使次级线圈中感应出电压（或电流）。是什么意思？

Transformer is transformed AC voltage, current and impedance of the device through the primary coil when there is AC current, the core (or core) will be generated in the exchange of flux, so that the secondary coil induces a voltage (or current).

AC voltage transformer is Fourier Transform and impedance of the device, and current, if the primary coil links with AC current, when iron core (or core) are produced in magnetic flux, and exchange in the secondary coil sensor output voltage (or current).

The transformer may divide into according to the use: The distribution transformer, the power transformer, all seal the transformer, the combined transformer, the dry transformer, the oil bath type transformer, the single phase transformer, the electric stove transformer, the rectification transform

Transformers is the transformation of AC voltage, current and impedance devices, when you pass AC current primary, iron core (or cores) occurs in AC magnetic flux so that induction voltage in the secondary coil (or current).
