Efficiency studies on transformers

Almost all transformers get hot, so they are consuming some electricity. In other words not all the electricity entered in the primary coil, exists from the secondary coil. The ratio of the produced electricity to the consumed electricity is the efficiency rate of a transformer.
 Project description:
In this project you will experiment measuring the efficiency of a transformers. You will then study and experiment to see what factors may affect the efficiency of transformers. Some of the questions related to transformers are: 
  1. How does the amount of load affect the efficiency of a transformer?
  2. How does the type of core material affect the efficiency of transformers?
  3. How does the number of windings in the primary coil affect the efficiency of a transformer?

Before you choose any of the above questions, you must make sure that you can find the necessary material for your experiments. Material that you need for the question number 1 are a transformer, a multi-meter and some other wires and electrical components.
