Explain, why electric power is transmitted at low current to distant places .

Text Solution

Verified by Experts

Electrical power P = VI = `1^(2) R` and from Ohm.s law, V = IR . At constant resistance, electrical power is directly proportional to voltage and square of current. Thus, if current is kept low, power loss during transmission is reduced significantly.
