- Low voltage winding can be primary or secondary. Low voltage winding carries a higher current and hence the resistance of winding is less.
- As the resistance of winding is inversely proportional to the area of cross-section, the area of low voltage winding is more compared to high voltage winding.
Additional InformationThe turns ratio for a transformer is given by:
where N1 and N2 are primary and secondary turns
V1 and V2 are primary and secondary voltage
