G5C05 : Why is the primary winding wire of a voltage step-up transformer usually a larger size than that of the secondary winding?
A To improve the coupling between the primary and secondary
B To accommodate the higher current of the primary
C To prevent parasitic oscillations due to resistive losses in the primary
D To ensure that the volume of the primary winding is equal to the volume of the secondary winding
Correct Answer: To accommodate the higher current of the primary
