# Power transformer winding

## Recommended Posts

8) Since long time I search about formulas used in winding a new transformer such that determining core area, primary and secondary number of turns and wire diameter etec
Please if you Know them tell me.
thanks

Hi everybody
May i kno if we get sqare wave input to transformer why does it  give at o/p ; a squrewave  or  pulses like derivative of square? According to theory the o/p emf shud generate only by d/dt  of  i/p  flux.  And in squ-wave input is constant  except the edges of square wave. So there shud not be any o/o emf  for this constant voltage part of squ-wave.

Hi
Ante
Y  do u make me read all this theory from 12th standard to B.E. final?
Tell me conclusion.

Hi aakaash,

Why would I read it to get your specs right, its much better that you read it and understand it! I provide you with information; do you want me to do your work too?
