O Level Magnetism with KYM || Lesson 6 || Transformer Questions and Relay Circuits

Welcome to Lesson 6 of O Level Magnetism with KYM! In this video, we put your knowledge of electromagnetic induction to the test by tackling challenging transformer calculation questions and exploring the practical applications of relay circuits. We will walk through step-by-step solutions for past-paper problems involving step-up and step-down transformers, voltage ratios, and power efficiency. Whether you are struggling with the transformer equation or need to understand exactly how magnetic switches operate for your Cambridge O Level and IGCSE Physics exams, this lesson provides the exact problem-solving strategies you need to maximize your marks. #OLevelPhysics #IGCSEPhysics #Transformers #RelayCircuits #Magnetism #PhysicsWithKYM #GCSEPhysics
