An electric power is transmitted over a long distance through conducting wire at high voltage and low current because:
Correct answer: A. It causes less amount of power loss
- A. It causes less amount of power loss
- B. It reduces the possibility of power theft
- C. High voltage waves travel faster
- D. Generators produce electrical energy at high voltage
Explanation
High voltage is used to increase efficiency and low current is used to reduce resistance which causes less power loss, hence Option A is correct.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
