_______________is universally used for windings of electrical machines because it is easily workable without any possibility of fracture?
Correct answer: D. Copper
- A. Silver
- B. Steel
- C. Aluminium
- D. Copper
Explanation
Copper is used most widely for machine windings because it combines high electrical conductivity with ductility, allowing it to be drawn, bent, and wound without fracturing. Silver conducts better but is far too costly for general windings.
