- 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. Where , a and k are a constant For Step Up transformer- a >1 N2>N1,V2>V1 Step down transformer- a <1 N2<N1,V2<V1
