The following arrangement consists of an ideal transformer and an attenuator
which attenuates by a factor of 0.8. An ac voltage V

_{wx1}= 100V is applied across WX to get an open circuit voltage YZ1 V across YZ. Next, an ac voltage V_{YZ2}=100V is applied across YZ to get an open circuit voltage V_{WX2}across WX. Then, V_{YZ1}/ V_{WX1}, V_{WX2}/ V_{YZ2}are respectively,2
