An ideal transformer with purely resistive load operates at 12 kV on the primary side. It supplies electrical energy to a number of nearby houses at 120 V. The average rate of energy consumption in the houses served by the transformer is 60 kW. The value of resistive load $$(R_s)$$ required in the secondary circuit will be ______ m$$\Omega$$.

We have a transformer with primary voltage $$V_p = 12\;\text{kV} = 12000\;\text{V}$$, secondary voltage $$V_s = 120\;\text{V}$$, and average power consumption $$P = 60\;\text{kW} = 60000\;\text{W}$$.

For an ideal transformer, power is conserved. The current in the secondary circuit is

Now the resistive load in the secondary circuit is

Hence, the value of the resistive load is $$240$$ m$$\Omega$$. So, the answer is $$240$$.
