Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:24) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 62.5 mA exists in the primary of the transformer. The secondary is connected to the primary of another step-down transformer (turns ratio =...
