Question

A transformer connected to 220 V line shows an output of 2 A at 11000 V. The efficiency is 100 %. The current drawn from the line is (A) 100 A (B) 200 A (C) 22 A (D) 11 A

(Vs/Vp)=(ip/is) ⇒ ip=(11000 × 2/220) =100 A

Q. A transformer connected to $220 V$ line shows an output of $2 A$ at $11000 V$ . The efficiency is $100%$ . The current drawn from the line is

100 A

200 A

22 A

11 A

$\frac{V _{s}}{V _{p}} = \frac{i _{p}}{i _{s}}$
$\Rightarrow i_{p} = \frac{11000 \times 2}{220}$
$= 100 A$
