Secondary and primary windings consist of ________(a) copper turns(b)

1.	Secondary and primary windings consist of ________(a) copper turns(b) 14 S.W.G copper wire and copper strip respectively(c) iron coils wound around(d) laminationsThe question was asked by my college professor while I was bunking the class.Asked question is from Design Features of Current Transformers topic in division Extension of Instrument Ranges of Electrical Measurements
Answer» Correct answer is (b) 14 S.W.G copper wire and copper strip respectively Easy explanation: For a current transformer the most popular FORM USED is the bar primary and ring core CONSTRUCTION. Hence 14 S.W.G copper wire is used for the secondary winding WHEREAS a copper strip is used for the primary winding.
