The two questions below.

Like will be given, thanks!

1. What is the advantage of winding the primary and secondary windings on the same limb of the core of a transformer? 2. The open circuit test on a 500 kVA, 69 kV / 4.16 kV, 60 Hz single phase transformer gave a wattmeter reading of 2400 W. The high voltage side was open and the measurements were taken on the low voltage side. What would be the reading of the wattmeter if the open circuit test is repeated by leaving the low voltage side open and taking the measurements on the high voltage side?
