When a DC voltage (like 6 V from a battery) is connected across the primary transformer, no steady secondary voltage is induced, transformers work based on electromagnetic induction, which requires a changing magnetic field.
Since DC provides a constant current, it doesn't create a changing magnetic field necessary for induction.
Therefore, the secondary voltage in this scenario would be 0 V.

For an emf to be induced, the magnetic field has to constantly change according to Faraday's law of electromagnetic induction. DC does not change as such the magnetic field will remain constant and no emf is induced.

Dc only provide stationary flux and tr is also stationary stationary machine. So these two are make 0 degree so these are not cut one another.

there is no secondary side windings because the ratio is given as 8 only at primary side so the output is 0.

Transformer works on the principle of mutual induction & for dc supply, no induction would take place.

Constant supply gives constant flux but flux will not linkage with stationary conductor so no induce emf.

In DC supply occurs then the transformer winding is burn out so no output. That's why output is zero?

I think 6v DC is sufficient to burn transformer welding because cu winding resistance is too less.

Dc voltage porduce no flux varing field so no emf will be indused and no output will be gerated.

With dc input transformer gives zero secondary voltage. That means can't operate.
