This video visualizes the counter intuitive phenomenon of the transformers, when voltage is stepped up, the current gets stepped down. This is a consequence of energy conservation. Transformers work on the principle of electromagnetic induction - mutual induction. Power line transmission requires both step up and step down transformers.
