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

• A. 100 A
• B. 200 A
• C. 22 A
• D. 11 A

Answer 1

Answer: (A)

100 A

Answer 2

$\frac{V_{s}}{V_{p}} = \frac{i_{p}}{i_{s}} \Rightarrow i_{p} = \frac{11000 \times 2}{220} = 100\mspace{6mu} A$
