Daily Science Popularization-Transformer
Transformers, a device that changes the voltage of the power supply, vary greatly in size. From the small square box that changes household electricity to start model trains, to the large transformers in substations that can control extremely large electrical energy, they are all in one category.

The loss in the operation of the transformer includes two parts;(1) is caused by the iron core, when the coil is energized, because the magnetic lines of force are alternating, causing eddy current and hysteresis loss in the iron core, which is collectively referred to as iron loss. (2) It is caused by the resistance of the coil itself. When the primary coil and the secondary coil of the transformer have current flow, power loss will occur. This loss is called copper loss.

The structure of the voltage regulator is the same as that of the autotransformer, except that the iron core is made into a toroidal coil and wound on the toroidal iron core. The secondary coil tap uses a sliding brush contact to make the contact slide along the coil surface to achieve smooth adjustment voltage.

In Senior high school textbooks, the working principle of the transformer has been explained in detail. However, I am afraid that most people will forget it completely after the college entrance examination. But the knowledge is lost, the application is not lost, the transformer has penetrated into every corner of our lives. The transformer, which is so close to us that every ampere of current we use, flows out of the transformer. Within 1km of our location, there must be a transformer. You didn't notice, you just didn't notice.
