Question: In a transformer, the number of turns in primary and secondary are 500 and 2000 respectively. If current in primary is 48 A, the current in the secondary is [Orissa PMT 2004]
Options:
A) 12 A
B) 24 A
C) 48 A
D) 144 A
Show Answer
Answer:
Correct Answer: A
Solution:
$ \frac{N_{s}}{N_{p}}=\frac{i_{p}}{i_{s}}\Rightarrow \frac{2000}{500}=\frac{48}{i_{s}}\Rightarrow i_{s}=12A $
