4. A transformer on a utility pole operates at V1,rms=8.0 kV on the primary side and supplies electric energy to a number of nearby houses at V2.rms=120V. a) What is the turns ration N1/N2? b) if the average power consumption in the houses for a given time interval is 70 KW, what are the rms currents in the primary and secondary wirings of the transformer? Assume an ideal transformer, a resistive load and a poser factor of unity. c) what is the equivalent resistive load R in the secondary circuit?
