The Transformer: Simulation Lecture Demo
This material is replicated on a number of sites
as part of the
SERC Pedagogic Service Project
Summary
In a physics lecture, the class is presented with a simulation of the operation of a transformer. The students are presented with a question involving the qualitative relationship between the input and output emf and the number of turns in the primary and secondary coils. The starting point of the simulation is a transformer with equal number of turns on the primary and secondary. The students are asked how the output voltage changes as the number of turns in the primary and secondary is altered.
Learning Goals
The student should complete the activity with a qualitative understanding of the dependence of transformer operation on the parameters of the transformer. The student should also develop an improved understanding of Faraday's law.Context for Use
