- recall the structure of a transformer and understand that a transformer changes the size of an alternating voltage by having different numbers of turns on the input and output sides
- explain the use of step-up and step-down transformers in the large-scale generation and transmission of electrical energy
- recall and use the relationship between input(primary) and output(secondary) voltages and the turns ratio for a transformer: Primary voltage/secondary voltage = primary turns/secondary turns
