Question

Oscillations, Transformers)
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
(1) 220 V
so
NE
NS SO (2) 100 V
(4) ov
(3) 1000 V​

Answer 1

Answer:

1000 V​

Explanation:

Vi = 220

Ii = 2.2

Np / Ns = 11/50

Np / Ns = Vp /Vs

11/50 = 220 /Vs

Vs =1000 V​
