Course Curriculum
| Principles of Electromagnetic Induction: In this topic, students learn how a changing magnetic field induces an electromotive force (e.m.f.) in a circuit. Examples include Faraday’s experiments. Students also explore factors influencing induced e.m.f. |
| The AC Generator: This topic delves into AC generator operations, including rotating coils or magnets. Students examine the role of slip rings and sketch voltage output graphs to understand alternating current generation. |
| The Transformer: Students gain insights into the structure and operation of iron-cored transformers used for voltage transformations. They apply equations like VP / VS = NP / NS and VP IP = VS IS to solve problems. They also learn about energy losses in cables and the benefits of high voltage transmission. |
