k = sqrt(r2/r1).
k = sqrt(160/1000),
k = 0.4.
Therefore ratio will be 0.4:1.
k = sqrt(160/1000),
k = 0.4.
Therefore ratio will be 0.4:1.

sir..........
(N1/N2)^2=R1/R2
ABOVE ANSWER IS CORRECT SIR....
N1/N2=2.5:1
(N1/N2)^2=R1/R2
ABOVE ANSWER IS CORRECT SIR....
N1/N2=2.5:1

Answer should be a Turn and transform ratio is same N1/N2.
So answer A.
So answer A.

Z1/Z2=(N1/N2)^2
(1000/160)=(N1/N2)
^2
N1/N2=2.5:1
is the correct answer
(1000/160)=(N1/N2)
^2
N1/N2=2.5:1
is the correct answer

Is * 1000 = Ip * 160 and Ip/Is = k = N1/N2.
k = 1000/160 = 6.25:1.
k = 1000/160 = 6.25:1.

Option c because N IS INVERSELY PROPOTIONAL TO THE RESISTSNCE.

Saritha I think your answer is wrong once you calculate again.

Therefore Is*1000=Ip*160 and Ip/Is=k=N1/N2
k=1000/160=6.25:1
k=1000/160=6.25:1
