A) 100 V, 16 A
B) 40 V, 40 A
C) 160 V, 10 A
D) 80 V, 20 A
Correct Answer: B
Solution :
Given, \[{{N}_{p}}=500\]turns, \[{{N}_{s}}=2500,\] \[{{I}_{s}}=8A,\] \[{{e}_{s}}=200\] volt Transformation ratio \[(k)=\frac{{{N}_{s}}}{{{N}_{p}}}=\frac{{{e}_{s}}}{{{e}_{p}}}=\frac{{{I}_{p}}}{{{I}_{s}}}\] \[\therefore \] \[\frac{{{N}_{s}}}{{{N}_{p}}}=\frac{{{e}_{s}}}{{{e}_{p}}}\] \[\frac{2500}{500}=\frac{200}{{{e}_{p}}}\] \[\therefore \] \[{{e}_{p}}=40volt\] Again, \[\frac{{{N}_{s}}}{{{N}_{p}}}=\frac{{{I}_{p}}}{{{I}_{s}}}\] \[\frac{2500}{500}=\frac{{{I}_{p}}}{8}\] \[{{I}_{p}}=40A\]
