Thank you all for the given explanation.

@ALL.

If you test between neutral and ground on a transformer what is the problem and if test a phase and earth and there is 10v what is the problem but other phases are ok.

In phase means an angle between voltage and current is zero and out of phase means some angle between voltage and current.

Well said @Naresh.

Dot against inductors determine the phase difference of source and load. Dots in opposite directions means that load is at 180 degrees out of phase with source.

V1/V2= N1/N2.

40/V2 = 3/1.

V2 = 40/3.

V2 = 13.33 V OUT OF PHASE DUE TO OPPOSITE POLARITY.

Please can anyone say that what is the effect of 'in phase' and 'out of phase' ?

The dots represents same sign. Those dots are opposite sides so it is out phase.

How can we say whether it is in phase or out of phase?

Secondry coil voltage=40v.
Turn ratia=3:1
acording formula,
Np/Ns=Vp/Vs
3/1 =40/Vs
Vs=13.33v
