Q. 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) $11\ A$
Explanation
(a) $\frac{V_{s}}{V_{p}} = \frac{i_{p}}{i_{s}} \Rightarrow i_{p} = \frac{11000 \times 2}{220} = 100\ A$
