    An ideal transformer with purely resistive load operates at 12kV12kV on the primary side. It supplies electrical energy to a number of nearby houses at 120 V120\text{ }V. The average rate of energy consumption in the houses served by the transformer is 60 kW60\text{ }kW. The value of resistive load (Rs) required in the secondary circuit will be ___mΩ\_\_\_ m\Omega.
