Electro Magnetic Induction And Alternating Currents Question 272

Question: A step up transformer has transformation ration 5 : 3. What is voltage in secondary if voltage in primary is 60 V [Pb. PET 2000]

Options:

A) 20 V

B) 60 V

C) 100 V

D) 180 V

Show Answer

Answer:

Correct Answer: C

Solution:

Transformation ratio $ k=\frac{V_{s}}{V_{p}}\Rightarrow \frac{5}{3}=\frac{V_{s}}{60}\Rightarrow V_{s}=100\ V $
