Here [always] turns ratio is H.V/L.V side

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.
N2/N1 = turn ratio.
2000/400 = 5.

Turns ratio = N2/N1.
N2 = 2000.
N1 = 400.
T.R = N2/N1 = 2000/400 =5.
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.
But when we find the voltage or turn ratio it will reverse.
Voltage ratio = Vs/Vp.
Turn ratio = Ns/Np.

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?

We know That turns Ratio is inversely proportional to the secondary wdg. & primary wdg.
Turns ratio (K) = Secondary wdg(N2) / Primary wdg (N1).
K = 2000/400.
= 5.
Turns ratio (K) = Secondary wdg(N2) / Primary wdg (N1).
K = 2000/400.
= 5.

I remove your all confusion dears turn ration is always in the form of high voltage/low voltage it does not matter turn ratio is n1/n2 or n2/n1 we just take turn ratio is as the number of turns in high voltage side divided by no of turns in low voltage side so the answer five is correct ok to all of you.

This is all wrong turns ratio is N1/N2. So the answer is 0.2.
