A transformer works basically by means of an electromagnet whose magnetic fields induce a current in adjacent coils, but of a different voltage. The electromagnet has wires through which a current flows. Since the wire has a resistance greater than zero (it is not a superconductor) there is going to be some waste heat produced as a result. And the more current, the more heat. If a transformer is used for currents beyond those for which it was designed, it will therefore overheat.
When we give d.c supply to a transformer the primary winding will burn because constent flux will be will be produced which doesnt link with secondary so max current will circulate on primary winding only
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
It doesn't really matter which way around you use a transformer, the primary winding is ALWAYS whichever winding you connect to the supply, and the secondary winding is ALWAYS whichever winding you connect to the load. For either connection, the turns ratio will ALWAYS equal the voltage ratio for an ideal transformer (or close enough for a real transformer).
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
the winding would burn....
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.
It depends on the rated voltage of the transformer winding -are you talking about a 12-V transformer winding or a 400-kV transformer winding? Obviously, there is no one answer to your question!

A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.
