Why is electric power transferred at high voltage and low current to distant places?
 
Asked by Ra. | 23 Sep, 2015, 05:48: PM
answered-by-expert Expert Answer
The power from the generating station is transmitted over long distances at a higher voltage to minimise the loss of energy in the form of heat in the line wires used for transmission. 
Wire resistance causes losses in eletric power transmission. 
For a given electric power, the current becomes low at a high voltage and therefore, the loss of energy due to heating (H = I2Rt) in the line wires becomes less.

The flow of electrons is opposite to the direction of the flow of current as electron is negatively charged . Then why current is defined as the flow of electrons through the conductor though current travels from positive to negative terminal.
