Question

In an ideal transformer no. of turns in the primary and secondary coil are 200 and 1000 respectively

Answer 1

hope it helps you jii ✌

Here, np=2000  ,  ns=1000
         Ep = 200 V  
let output voltage = Es
(a)
      For a transformer,      EsEp=nsnpEs=Ep(nsnp)=200 V×(10002000)=100V

(b)  Power input ,Pp = 10 kw = 10,000 w  
      Input current , Ip=PpEp=10,000 w200V=50 A
