An ideal transformer (with sufficiently large inductance and sufficiently low resistance) can pass DC, but real transformers are not ideal and only work with AC. This transformer passes DC at first, but after a short time, the DC voltage fades due to resistance in the primary and the finite inductance of the transformer coils. -- Credits: Mr. Paul Falstad.

|How culd you make it work?
But the current is changing and it may work with less theory. :)

|If we apply sawtooth in primary, what will be the output. . . ?|

|@ Nijil V V.
When the transformers are applied with sawtooth waves, then it will provide a similar wave at output, but with humming noise and heating effect which may cause damage to primary winding of transformer.

|Transformer works with constant frequency. But in dc we don't have frequency. How it works?|
