The use of higher flux density in the transformer design ---
- A. decreases the total weight / kVA
- B. increases the total weight / kVA
- C. decreases the weight of iron / kVA but increases that of copper
- D. decreases the weight of copper / kVA but increases that of iron
Answer: A. decreases the total weight / kVA
Explanation: Higher flux density permits a smaller core and winding, reducing total weight per kVA.
