We know that e=N(dflux/dt).
For dc supply flux is constant and derivative of constant is zero. So emf induced in secondary becomes zero i.e, e=0.
For dc supply flux is constant and derivative of constant is zero. So emf induced in secondary becomes zero i.e, e=0.

The transformer will work on only A.C supply/source. But the battery will provide only D. C source & transformers don't act in D.C source.

It only works A.C so the voltage across the lad is definitely zero.

If it is AC supply then answer is 0.

N2/N1=V2/V1,
3/1=V2/6,
V2=2.
V=IRL,
I=V/RL,
I=2/100=1/50.
Now calculate Voltage across load,
V=IRL,
2=1/50*100,
= 0.
3/1=V2/6,
V2=2.
V=IRL,
I=V/RL,
I=2/100=1/50.
Now calculate Voltage across load,
V=IRL,
2=1/50*100,
= 0.

Transformer working is only ac supply but battery provide dc supply doesn't question work on transformer.

Transformer not works on AC supply so the answer is 0V.

Transformer will works on AC volatge if we give DC voltage to transformer it may be burnt or damage the winding.

Transformer working only with AC source.

The transformer is not working on the DC source.
