A transformer on a utility pole operates at an Vp = 8:5 KV rms on the primary side and supplies electric power to a number of nearby houses at Vs = 120 V rms. The average power consumption in the houses served at a given time is 75 KW. Assume an ideal transformer, a resistive load and a power factor of unity.

(a) What is the turn ratio, Np=Ns, of this step-down transformer?

(b) What are the rms currents in the primary and secondary windings of the transformer?
