Effects of Harmonics on Transformers
The transformer does not generate harmonics. The transformer has primary and secondary windings, which are inductive. The inductive load draws current linearly with the applied … Read more
What is Self Inductance? Definition and Explanation
The coil opposes the change of current flowing through it. This property of the coil is called Self-inductance. The opposition offered by a coil depends on the … Read more
