An ac voltage $V_{WX1}=100V$ is applied across $WX$ to get an open circuit voltage $Y_{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 $80/100$ Electrical Machines gate2013-ee turn-ratio primary secondary + – piyag476 572 views answer comment Share Follow 0 reply Please log in or register to add a comment.
