Question

A step-up transformer operates on 220 V line and supplies 2.2 A. The ratio of primary and secondary winding is 11: 50. The output voltage in the secondary is (A) 220 V (B) 100 V (C) 1000 V (D) 0 V

(NP/NS)=(Vp/VS) VS=(NS VP/NP) =(50/11)(220) =1000 V

Q. A step-up transformer operates on $220 V$ line and supplies $2.2 A .$ The ratio of primary and secondary winding is $11 : 50$ . The output voltage in the secondary is

220 V

100 V

1000 V

0 V

$\frac{N _{P}}{N _{S}} = \frac{V _{p}}{V _{S}}$
$V_{S} = \frac{N _{S} V _{P}}{N _{P}}$
$= \frac{50}{11} (220)$
$= 1000 V$
