Episode 416: Generators and Transformers

Comments (0)

Produced by the Institute of Physics, these discussions and demonstrations show that in a generator, motion of a conductor in a magnetic field induces an electromotive force (emf). In a transformer, it is the changing field that induces an emf in a fixed conductor.

The activities in this learning episode include:
• discussing generators
• questions on AC generators
• demonstrating transformers
• transformer equations
• considering practical transformers

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
