For long distance electrical power transmission, we use:
Correct answer: D. Smaller current and higher voltage
- A. Smaller current and lower voltage
- B. Larger current and higher voltage
- C. Larger current and lower voltage
- D. Smaller current and higher voltage
Explanation
Option D is correct. This is the most efficient method for long-distance electrical power transmission. By stepping up the voltage, it's possible to decrease the current, which in turn reduces resistive losses in the transmission lines, making the transmission more efficient.

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.
