Expert Solution
Step 1
Assuming high voltage is connected to left windings.
on primary side consisting of two coils in series where as on secondary two coils are connected in parallel. so secondary Phase(or line) voltage is same as per coil voltage (because they are in parallel) where as Primary phase (or line)voltage is double the per coil voltage ( because they are in series)
