The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of 0.8. An ac voltage Vwx = 100 V is applied across WX to get an open circuit voltage Vyz across YZ. Next, an ac voltage Vyzz = 100 V is applied across YZ to get an open circuit voltage Vwx2 across WX. Then, Vyz/Vwx. Vwx2/Vyz2 are respectively, W 1:1.25 OY Xo (A) 125/100 and 80/100 (C) 100/100 and 100/100 Z (B) 100/100 and 80/100 (D) 80/100 and 80/100 The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of 0.8.
