The purpose of this experiment is

  • To investigate the characteristics of a transformer
  • How a transformer is really not ideal, RS efficiency is low and AC resistance is high.
  • To show that AC resistance of the windings acts like series- dropping resistance.
  • 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.
  • How using only one half of the tapped winding doubles turns-ratio.
  • To demonstrate how loading the secondary winding increases the current in the primary of the transformer.
  • To demonstrate the principles of an AUTO TRANSFORMER.
