प्रश्न
In the transmission of power the voltage of power generated at the generating stations is stepped up from 11kV to 132 kV before it is transmitted. Why?
उत्तर
For electric power, the current becomes low at a high voltage. So, according to the relation I2RT, the loss of energy due to heating in the line wire becomes less. Thus, the alternating voltage generated is first stepped up from 11 kV to 132 kV at the generation station.
