For transmission of electricity to far off places, from the A.C. power generation via we always use:
Correct answer: C. Step up transformer
- A. Step down transformer
- B. Transformer with several secondaries
- C. Step up transformer
- D. All of these
Explanation
The explanation is: A step-up transformer increases the voltage while decreasing the current. This allows for efficient long-distance transmission of electricity with reduced losses. The high-voltage electricity is then transmitted over the power lines.

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.
