Question

when the Electricity generated in power station is transmitted to distant place energy is lose at heat ​

Answer 1

Answer:

The transmission over long distances creates power losses. The major part of the energy losses comes from Joule effect in transformers and power lines. The energy is lost as heat in the conductors. The overall losses between the power plant and consumers is then in the range between 8 and 15%

Answer 2

When power is transmitted from power station to different different substation then one important factor is kept in mind that power loss in pathway during transmission over large distances should be minimum.

we know that P = V I

so for a particular power that is to be transmitted we can choose a combination of voltage and current so that loss is minimum as much possible.

if we do current high and voltage minimum then due to high current , heat loss will be more and power will get lost , hence voltage is kept high and current is kept low as much possible so that current can not produce high vibrations and collisions in free electrons insides the wire making a lot of loss of power.

so by keeping voltage to high value the loss is minimum as compared to other cases.
