Turns Ratio = N2/N1 , So N2/N1 = 2000/400 = 5

We know T/F ratio

Turn ratio k=n2/n1=e2/e1=i1/i2
(Wed, Aug 31, 2011 05:37:38 PM)
We know that:- Turn ratio=N2/N1;
(Mon, Oct 24, 2011 11:07:04 AM)
I think its wrong because turns ratio is different from transformation ratio transformation ratio k=1/n=V2/V1=I1/I2

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.
2000/400 = 5 ans.
(Mon, Dec 26, 2011 07:13:12 AM)
turns ratio=1/k= N1/N2

Primary turns (n1) =400.
Secandary turns (n2) =2000.
Turns ratio (k) = n2/n1.

How can we say the answer is 5 ? Because in this problem you are mentioned primay is 400,secondary is 2000.
So my answer is turns ratio is 0.2 .
Here somebody said the answer is 5. They mentioned clearly in the problem primary turns is 400, secondary turns is 2000.
Please tell the reason clearly.

TURN RATIO FORMULA=SECONDARY TURNS(N2)/PRIMARY TURNS(N1).
SO, VALUE OF N2=2000 AND VALUE OF N1=400.
=>2000/400=5. THIS IS ANS.

This Is Ans

But actually the formula for turns ratio is N1/N2 so the answer will be 0.2.
Please reply why all taken it as N2/N1.
(Sat, May 12, 2012 03:46:10 PM)
so much confusion in the formula
Turn ratio is N1/N2 or N2/N1.
you have tried both the formula in two questions given here.

We know turn ratio = (turn on h. V) / (turn on l. V).
Turn ratio = 2000/400.
Turn ratio = 5.
(Wed, Jul 18, 2012 01:17:29 PM)
Transformation ratio = Vs/Vp = Es/Ep = Ns/Np = Ip/Is.
= Ns/Np = 2000/400 = 5.
(Wed, Aug 22, 2012 10:55:40 PM)
Here [always] turns ratio is H.V/L.V side
(Fri, Aug 24, 2012 12:31:07 AM)
turns ratio =h.v(less current ,more turns)/l.v(more current, less turns)=2000/400=5

Difference between turn and voltage ratio.

Secondary turns divided by the primary turns gives turn ratio.
N2/N1 = turn ratio.
2000/400 = 5.

Turns ratio = N2/N1.
N2 = 2000.
N1 = 400.
T.R = N2/N1 = 2000/400 =5.

When we find the single voltage and number of turn then we use Vp/Vs = Np/Ns.
But when we find the voltage or turn ratio it will reverse.
Voltage ratio = Vs/Vp.
Turn ratio = Ns/Np.
(Tue, Apr 30, 2013 11:30:40 PM)
We know transformation ratio to be NP/NS=VP/VS=IS/IP.
Now how come the answer is 5 instead of 0.2.
Please can you come out clear with your formuler explanation?
