#SaveMyExams #GCSEPhysics #IGCSEPhysics Electromotive force and potential difference are two of the most important electricity topics in GCSE and IGCSE Physics — and they’re often confused in exam questions. In this video, we explain electromotive force (EMF) and potential difference clearly and simply, helping you understand the difference between them and how they appear in Physics exams. You’ll learn: How electrons are driven through a circuit The role of cells in driving current by overcoming electrostatic forces How energy is transferred within circuits The critical difference between EMF and potential difference Whether you’re revising for mocks, homework or final exams, this video will help you strengthen your understanding of electricity and improve your confidence with Physics calculations and definitions.
