For a core-type power transformers, both primary and secondary windings have circular coil sections, because this section
  • a)
    has the strongest mechanical shape.
  • b)
    results in less core material and, therefore, less core loss.
  • c)
    is easier to wind.
  • d)
    require minimum conductor material and, therefore, less I2R loss.
Correct answer is option 'D'. Can you explain this answer?

The main reason for using circular winding instead of oval or square or any other shape is for the uniform distribution of radial forces and their effects throughout the windings. the fact that it requires the least amount of conductor is merely a plus point..
