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,
A
125 / 100 and 80 / 100
B
100 / 100 and 80 / 100
C
100 / 100 and 100 / 100
D
80 / 100 and 80 / 100
