Answer / rabi

As the rate of change of flux that links with primary and
secondary is same. so induced emf by per unit turn is same
for both secondary and primary.

Answer / gtmanikandan

voltage induced per turns(emf/turn)
=system rated voltage /total number of truns for both
primary or secondary

according to above formule ,both primary and secondry
indce voltage per turn equal

Answer / saranya

E2/E1=N2/N1(Voltage transformation ratio)
E2/N2=E2/N1.so the emf per turn is same.

Answer / ai hamid mir

voltage per turn of transformer is same because voltage per
turn of transformer is same.

Answer / santanu das

Since the same amount of flux links primary as well as
secondary windings, the induced emf per turn is same for
primary and secondary windings. That's why, per turn
induced emf:

E1/N1=E2/N2= f*Fimax*Sin(wt-pi/2); if flux, Fi=Fimax*sinwt.

Plz help me anyone. plzzzzzzzzzzzzzzzz

Answer / rizwan ansari

current density is estimated 1000-3000 per square inch but
for middle type operations it is taken 2000.

now: take the b0bn size 1*1*1 inches and supply volts are
200 then formula for primary turns is turns*volt=8*200=1600

if want output 6v,12v for this multiply

turn*volt=8*6=48 for 6 volts
turn*volt=8*12=96 for 12volts respectively.

why we use star and delta connection?why we donot give the supply directly?
