Transformer with Multiple Coils — Lesson 7

This lesson covers the concept of ideal transformers and their role in circuit analysis. It delves into the intricacies of how to solve circuits involving several ideal transformers. The lesson explains the concept of impedance and how it gets transferred across the secondary coil of a transformer. It also discusses the concept of voltage per turn, which remains constant in several coupled coils. The lesson further elaborates on how to calculate the induced voltage. The lesson also provides a detailed explanation of how to calculate currents in all the windings of a transformer when different switches are closed.
