Transformer | Electromagnetic Induction | O-Level & IGCSE Physics | Part 7 | Physics with sms

Описание: In this lecture, we explain the Transformer, an important application of electromagnetic induction in IGCSE & O-Level Physics. This topic is frequently tested in Cambridge examinations, both in theory and numericals.

📘 Topics covered in this video:
✅ Definition of a transformer
✅ Principle of operation (electromagnetic induction)
✅ Labeled diagram of a transformer
✅ Role of primary coil, secondary coil, and soft iron core
✅ Step-up and Step-down transformers
✅ Transformer equation:
 Vp / Vs = Np / Ns
✅ Energy losses in a transformer
✅ Methods to reduce energy losses
✅ Why transformers work only with AC
✅ IGCSE & O-Level exam-style questions

🎯 This lesson is ideal for:
✔️ IGCSE Physics (0625) students
✔️ O-Level Physics (5054) students
✔️ GCSE Physics learners
✔️ Students revising electromagnetic induction & electricity
