Transformer help required "urjent" ?

[yusuf.businessmen]

I have a transformer which is 250:6volt means input is 250v and output is 6volt.
I want 250v output and 6v input can i accomplish this by giving supply voltage on secondary(6v).

thanks in advance

yes , you can do that, but depend on the transformer winding there may be a slight variation in output

If your transformer is ideal than yes, you will have 250V, otherwise you will get a higher voltage.

Yes, as laszlof said if it's an ideal transformer you will get the 250v output. Because NsEs=NpEp=IpIs.
