Turns ratio=n2/n1,
so N2/N1=2000/40=5

Mahesh said:   1 decade ago
Turns Ratio = N2/N1 , So N2/N1 = 2000/400 = 5

Sandhya said:   1 decade ago
2000/400=5
because,
turns ratio=n2/n1

We know T/F ratio
k=n2/n1
so 2000/400=5
Ratio=5

Ranchod gurjar said:   1 decade ago
Turn ratio k=n2/n1=e2/e1=i1/i2

n2/n1=2000/400=5

We know that:- Turn ratio=N2/N1;

HERE N2=2000;
N1=400;
T.R=2000/400=5

I think its wrong because turns ratio is different from transformation ratio transformation ratio k=1/n=V2/V1=I1/I2

n=v2/v1
n=2000/400
n=5

Transformer ratio is always mention in the form of N1/N2 so I suppose that the answer should be 0.2 because N1 showing primery & N2 is secondary. If answer is 5 than 2000 should be primary & 400 should be secondary.

Turn ratio =N2/N1 or V2/V1.
As given
N2=2000
N1=400
so-
2000/400 = 5 ans.
