A) 1.1V
B) 25V
C) 18V
D) 11 V
Correct Answer: A
Solution :
From transformer ratio \[\frac{{{V}_{s}}}{{{V}_{p}}}=\frac{{{N}_{s}}}{{{N}_{p}}}\] \[\Rightarrow \] \[{{V}_{s}}=\frac{{{V}_{p}}\times {{N}_{s}}}{{{N}_{p}}}\] \[=\frac{220V\times 40000}{200}=44000\,V\] Potential difference per turn is \[\frac{{{V}_{s}}}{{{N}_{s}}}=\frac{44000V}{40000}=1.1\,V\]
