What is the difference between transformers and inductors
high frequency magnetic circuit can be open, such as iron oxygen and air core coil, low frequency magnetic circuit is closed, such as iron core and ferrite core
made of silicon steel sheet iron core when the frequency is low, with a ferrite core for high frequency, high frequency is air core coil
A wide range of inductors and Transformers: working frequency is the frequency (50Hz), can also be a radio waves (such as more than a few hundred MHz
