A) 1
B) Greater than one
C) Less than one
D) The ratio greater or less than one depends on the other factors
Correct Answer: B
Solution :
Transformation ratio \[k=\frac{{{N}_{s}}}{{{N}_{p}}}=\frac{{{V}_{s}}}{{{V}_{p}}}\] For step-up transformers, \[{{N}_{s}}>{{N}_{p}}\ i.e.\ {{V}_{s}}>{{V}_{p}},\] hence \[k>1.\]You need to login to perform this action.
