Q. The transformation ratio in the step-up transformer is
A) One
B) Greater than one
C) Less than one
D) The ratio greater or less than one depends on the other factors
Explanation
(b) Transformation ratio,$\ k = \frac{N_{s}}{N_{p}} = \frac{V_{s}}{V_{p}}$
For step-up transformer,
$N_{s} > N_{p},\ \ ie,V_{s} > V_{p},\ hence,\ k > 1.$
