T₃=10.4
T₄=10.6
by v=
we get
V₁=
V₁=10m/s
V₂=
V₂=9.8m/s
V₃=
V₃=9.61 m/s
V₄=
V₄=9.43 m/s
V₁:V₂:V₃:V₄ = 10 : 9.8 : 9.61 : 9.43

As we know that in transformers we have
here we know that
now from above equation we will have
now we have to reduce this voltage to final voltage of V = 4 V
so again we will have
so we need to take such a winding whose ratio is 1:5
So it is satisfied in X
so answer will be
<u>B)- X</u>
