Electro Magnetic Induction And Alternating Currents Question 253
Question: A transformer connected to 220 volt line shows an output of 2 A at 11000 volt. The efficiency is 100%. The current drawn from the line is [MP PMT 1995]
Options:
A) 100 A
B) 200 A
C) 22 A
D) 11 A
Show Answer
Answer:
Correct Answer: A
Solution:
$ \frac{V_{s}}{V_{p}}=\frac{i_{p}}{i_{s}}\Rightarrow i_{p}=\frac{11000\times 2}{220}=100\ A $
