4. EMF EQUATION

5. N1 -No. of turns of the primary winding
N2 -No.of turns of the Secondary winding
V1 – Supply AC voltage in volts
V2 - AC Load voltage in volts
f - Supply frequency in hertz

6. TRANSFORMATION RATIO /TURNS RATIO
 The transformer turns ratio is the number of turns of the primary
winding divided by the number of turns of the secondary coil.
 The transformer turns ratio provides the expected operation of
the transformer and the corresponding voltage required on the
secondary winding.
