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.

Please solve this.

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.

Transformers always operated on AC, so DC can't work.

When the transformer give the dc supply the core is saturate.

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

Transformer allows only ac voltage but not dc. So output is zero.

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.

Electromagnetic induction rule does not follow dc.

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