Question 49

In the construction of an efficient mains transformer, which choice correctly identifies the ideal materials for the coils and the core, along with the physical reason for their selection?

A

Coils: Copper (high electrical conductivity); Core: Soft iron (easily magnetized and demagnetized)

B

Coils: Soft iron (low electrical resistance); Core: Copper (easily magnetized and demagnetized)

C

Coils: Copper (low thermal conductivity); Core: Steel (retains permanent magnetism)

D

Coils: Aluminium (high magnetic permeability); Core: Soft iron (high electrical resistance)
