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?
Toroidal transformer is one type of electronic transformers, has been widely used in household appliances and other high technical requirements of electronic equipment, its main use is as a power transformer and isolation transformer.
