Objectives of this experiment:
1. To investigate the characteristics of a transformer.
2. How a transformer is really not ideal, RS efficiency is low and AC resistance is high.
3. To show that AC resistance of the windings acts like series- dropping resistance.
4. The operation of a step-up and step-down transformer and relationship with turns-ratio, when the secondary is not loaded and when the secondary is loaded.
5. How using only one half of the tapped winding doubles turns-ratio.
6. To demonstrate how loading the secondary winding increases the current in the primary of the transformer.
7. To demonstrate the principles of an AUTOTRANSFORMER.
