In the power system, the transformer occupies a very important position, our daily life is also widely seen in the transformer equipment, so the transformer is very important, as a power person, we should have a more systematic and comprehensive understanding of the transformer
The magnetic cores of transformers include pot-type cores, RM-type cores, E-type cores, EC, ETD and EER-type cores, PQ-type cores, EP-type cores, EP-type cores, toroidal cores, etc.
Magnetic antenna coils in radios, high-frequency chokes in simple semiconductor radios, oscillating coils in superheterodyne radios, etc., are \ninductors.\nInductor commonly known as inductance coil or short coil, is also a common electronic components; But its use in circuits is much less than that of resistors and capacitors. So what exactly is inductance? What role can\nit play in the circuit?
