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 $
