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 $V_{YZ1}$ 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,
- $125/100\; and\; 80/100$
- $100/100\; and\; 80/100$
- $100/100\; and\; 100/100$
- $80/100\; and\; 80/100$
