A) 240 V, 5 A
B) 240 V, 10 A
C) 60 V, 20 A
D) 120 V, 20 A
Correct Answer: A
Solution :
\[\frac{{{N}_{s}}}{{{N}_{p}}}=\frac{{{V}_{s}}}{{{V}_{p}}}\Rightarrow \frac{200}{100}=\frac{{{V}_{s}}}{120}\Rightarrow {{V}_{s}}=240\ V\] also \[\frac{{{V}_{s}}}{{{V}_{p}}}=\frac{{{i}_{p}}}{{{i}_{s}}}\Rightarrow \frac{240}{120}=\frac{10}{{{i}_{s}}}\Rightarrow {{i}_{s}}=5\ A\]
