AC DC, Alternators & Dynamos, Microphones & Loudspeakers

Complete No-Prep DOUBLE length lesson (60+ slides) with exam questions, tasks and answers on Alternating and Direct Current (AC and DC) Alternators, Dynamos, Microphones and Loudspeakers for AQA GCSE (9-1) Science / Physics.

As a Secondary Science teacher, Deputy Headteacher, writer and examiner for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. This high quality lesson includes explanations, different types of in-lesson assessment (all with answers) and unique exam questions.

My lessons are ideal for non-Physicists - as a Biologist who retrained as a Physics teacher I know how to take learners on a journey that builds up their understanding step by step, while still going into a lot of depth. The preview video shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy.

What’s Included:

• Two Starters with answers
• Explanation slides in five “chunked” sections using animated diagrams
• Editable diagrams and animations which help aid understanding.
• Multiple questions in different question styles and difficulties - no need for worksheets. Each of the five “chunked” sections contains a set of “quick” questions and a set of “in-depth” questions.
• Exam-style questions - these are uniquebased on real exam questions but not just copied from exam boards (in fact there aren’t many exam questions available from the exam boards for this yet)
• Answers for all questions
• All easily editable to adapt to your teaching or to use in existing lessons.
• Slightly humourous, at points, if you like that sort of thing.

Learning objectives:

• Explain how the generator effect is used in an alternator to generate AC and in a dynamo to generate DC
• Draw and interpret graphs of potential difference generated in the coil against time.
• Explain how a moving-coil microphone and loudspeaker / headphone work.

The lesson was written for AQA GCSE Physics but is very likely to be applicable to other exam specifications.
