A) 4 A
B) 2 A
C) 6 A
D) 10 A
Correct Answer: B
Solution :
Given \[{{i}_{p}}=4\,A\], \[{{N}_{p}}=140\], \[{{N}_{s}}=280\] From the formula, \[\frac{{{i}_{p}}}{{{i}_{s}}}=\frac{{{N}_{s}}}{{{N}_{p}}}\] or \[\frac{4}{{{i}_{s}}}=\frac{280}{140}\] So. \[{{i}_{s}}=2\,A\]You need to login to perform this action.
