Course overview
Transformers use electromagnetism to transform an AC voltage by mutual induction. A basic knowledge of electromagnetic induction is necessary to understand how transformers are used in the transmission and distribution of electricity. The Transformer Basics training course explains magnetism, electromagnetism and the basic principles of electric voltage transformation.
This online training course includes:
- Magnetism
- Electromagnetism
