Electronics (DoD): Transformers
This video defines and explains the following terms in reference to transformers: action, step-up, step-down, and coefficient of coupling. It also explains voltage and current magnitude relationships in the primary and secondary of transformers. If displays the difference between symbols used to represent power, audio, rf, and auto transformers. Transformers are demonstrated with a PSM-6 Multimeter that tests equipment sufficiently to identify transformer opens, shorts and turn-ration as it relates to step-up and step-down.
