V1/V2= I2/I1

But V2=.025V1

Vi/0.25Vi= I2/I1
4=I2/I1

4I1= I2

Voltage and current are inversely propotional for transformer.

V2/v1= i1/i2,
V1=(1/4)v1.
((1/4)v1)/v1=i1/i2.
4(i1/i2).

I is increased v is decreased because V=1/I.

Ip/Is=1/4Vp whole divided by Vp
Is=4Ip

E2/E1=I1/I2
(1/4)E1/E1=I1/I2
I2=4I1
