Electro Magnetic Induction And Alternating Currents Question 242

Question: The transformation ratio in the step-up transformer is

Options:

A) 1

B) Greater than one

C) Less than one

D) The ratio greater or less than one depends on the other factors

Show Answer

Answer:

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. $
