Lesson-15.1.3- describe 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.PreviousLesson-15.1.5- know and use the relationship between input (primary) and output (secondary) voltages and the turns ratio for a transformer: input (primary) voltage/output (secondary) voltage = primary turns/ secondary turnsNext
