Electric transformers

Electric transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction. They are essential for the efficient transmission and distribution of electrical power. Here’s a breakdown of how transformers work and their key features: ### Basic Principles: 1. **Electromagnetic Induction**: Transformers operate on the principle of electromagnetic induction, a process where a changing magnetic field generates an electromotive force (EMF) in a coil of wire.
