Lesson building on knowledge of transformers and magnetic fields. Includes practice questions for students.
Ideal for AQA GCSE (9-1) P7, Cambridge iGCSE P9 and more.
Developing: Recall and use the equation Ip Vp = Is Vs (for 100% efficiency)
Secure: Describe the use of the transformer in high-voltage transmission of electricity.
Exceeding: Explain why power losses in cables are lower when the voltage is high.
