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 = 1:32) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-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.

I got 15390 and it is incorrect.

    Learning Goal: To understand the concepts explaining the operation of transformers.One of the advantages of alternating current (ac) over direct current (dc) is the ease with which voltage levels can be increased or decreased. Such a need is alwayspresent due to the practical requirements of energy distribution. On the one hand, the voltage supplied to the end users must be reasonably low for safety reasons(depending on the country, that voltage may be 110 volts, 220 volts, or some other value...

    Please Provide detailed solution. Thank you An average power of 65 kW is delivered to a distant farm via a transmission line that has a resistance R = 3.00 Ohm. The generator has an rms voltage V_1 = 500 V. A step-up transformer raises the voltage to an rms value V_2 = 10,000 V. Calculate the following: The rms value I_2 of the current on the transmission line The average thermal power (P_thermal) lost on the transmission line. The rms...

    The outlet voltage inside a house is 120V, but the voltage at the power line that supplies the neighborhood is much higher. A transformer between the power line and the house has 5000 turns in the primary coil and 500 turns in the secondary coil. What is the voltage of the power line supplying electricity to the neighborhood?
