What are the working principles and functions of power transformers?
When the primary winding of a transformer is connected to an AC power source, current flows in the winding, generating magnetic flux. This magnetic flux will pass through the iron core, causing alternating magnetic flux to be generated in the iron core. This process is like converting electrical ene......
