How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
If DC is applied to the primary of a transformer is there any current in the secondary and if there is then whether ac or DC?
first, understand that a transformer is an AC DEVICE. it wont work on dc...
Do pulse transformer is work on dc supply?

Why doesn't transformer work on a DC supply?
to have transformer action there should be an alternating magnetic flux.but dc supply cannot produce alternating flux.
Can booster transformer be used in dc distribution system?
No. Transformers work in AC systems, not in DC systems.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
Can a transformer work using dc?
no. because if we use dc source for transformer there will be no production of energy for the secondary side since they are mutually conducted, as the transformer is a static device which can transmite the energy from one circuit to other with out changing the frequency and also there is no movement of the conductors. in order to produce the emf there should be either conductor movement or moving flux so the dc source will produce constant field flux hence there is no production of energy in the secondary side.
If Transformer on a DC circuit?
Trsansformers work on mutual induction principle caused by the changing magnetic field. Since there is no changing magnetic field i.e there is no "+" and "-" cycle in DC source supply so transformer cant work on a DC source. Its core will become permanent magnet.
Why doesn't an AC appliance operate on DC?
Anything with a transformer in it will not work on DC because the transformer will draw enough current to blow the fuse (or catch fire) because transformers must always have a changing voltage. A simple heater will work on AC or DC. Appliances with most types of motor will only work on AC.
DC current is not used in transformer?
No. Transformers rely on the magnetic field changing direction to work, so DC can't be used.
If a dc voltage of 12v is added to the secondary of step down transformer and rating of transformer is 220 input and 12v output what will be the result from primary of transformer?
Adding a DC voltage to the secondary of a transformer will not have an effect on the primary side, as transformers work on the principle of electromagnetic induction which is based on alternating current. The primary side of the transformer will still operate based on the input AC voltage of 220V. The DC voltage on the secondary side will not be transferred to the primary side.
Transformer are used in circuits containing both dc and ac?
No transformers only work with AC.
