Physics · Alternating Current
An ideal transformer with a 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 (Rs) required in the secondary circuit will be:
- 1360 mΩ
- 2240 mΩ✓
- 3480 mΩ
- 4120 mΩ
Correct answer
240 mΩ
