The following arrangement consists of an ideal transformer and an attenuator
which attenuates by a factor of 0.8. An ac voltage Vwx1 = 100V is applied across
WX to get an open circuit voltage YZ1 V across YZ. Next, an ac voltage
VYZ2 =100V is applied across YZ to get an open circuit voltage VWX2 across WX.
Then, VYZ1 / VWX1 , VWX2 / VYZ2 are respectively,
