Why bother with a post grad course - waste of time? 17-10-2016
1. Describe 2 causes of the energy losses in a transformer and discuss how these energy losses may be reduced by suitable design and choice of materials. The quality of your written communication will be assessed in this question!

1) How do people approach this?

1) How do people approach this?
Learn the principles of how a transformer works through electromagnetic induction.
Understand the construction of a transformer and the use of various materials to accomplish the device.

Energy losses:

Ohmic power losses due to the resistance of conductors.
Eddy current losses of the transformer core.

Use low resistance conductors.
Laminate the core or use a torroidal design.

Is this all AQA spec? And yeah I wrote about the law's and I mention energy lose to heat and P=I^2 R and about an iron core.
