The transformation ratio in the step -up transformer is

A

1

B

greater than one

C

less than one

D

the ratio greater or less than one depends on the other factors

Text Solution

Verified by Experts

The correct Answer is:
B
Transformation ratio
k = `underset(S)(N)`/`underset(P)(N)`= `underset(S)(V)`/ `underset(P)(V)`
For step up transformer , `underset(S)(N)` gt `underset(P)(N)` i.e., `underset(S)(V)` gt `underset(P)(V)`
Hence k gt 1
