A) 25 A, 20 A
B) 20 A, 16 A
C) 25 A, 16 A
D) 40 A, 25 A
E) 40 A, 16 A
Correct Answer: C
Solution :
\[Efficiency=\frac{output\text{ }power}{input\text{ }power}\] Input power\[=5000\text{ }W,\] Input voltage\[=200\text{ }V\] \[\therefore \] Primary current, \[{{I}_{p}}=\frac{5000}{200}=25\,A\] Output power\[=5000\times \frac{80}{100}=4000W\] Output voltage\[=250\text{ }V\] Secondary current, \[{{I}_{s}}=\frac{4000}{250}=16\,A\]
