A) 1600 A
B) 20 A
C) 4 A
D) 1.5 A
Correct Answer: C
Solution :
\[\frac{{{N}_{s}}}{{{N}_{p}}}=\frac{{{V}_{s}}}{{{V}_{p}}}\Rightarrow \frac{1}{20}=\frac{{{V}_{s}}}{2400}\Rightarrow {{V}_{s}}=120\ V\] For 100% efficiency \[{{V}_{s}}{{i}_{s}}={{V}_{p}}{{i}_{p}}\] \[\Rightarrow 120\times 80=2400\ {{i}_{p}}\Rightarrow {{i}_{p}}=4\ A\]
