High-voltage transmission line that distributes the power

Reference no: EM13538720

Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume that your house is the only one using electric power. At a substation the primary coil of a step-down transformer (turns ratio = 1:28) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 47.6 mA exists in the primary coil of this transformer. The secondary coil is connected to the primary of another step-down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary coil of this transformer delivers a 220-V emf to your house. How much power is your house using? Remember that the current and voltage given in this problem are rms values.
