Transformer Turns Ratio

Formulas

Np/Ns = Vp / Vs

Is = Ip x Np/Ns (ideal transformer)

Power = Vp x Ip = Vs x Is

An ideal transformer conserves power. Real transformers have 90-98% efficiency due to copper and core losses.

हल किया गया उदाहरण

120 V primary to 12 V secondary, 0.5 A primary current.

  1. Turns ratio = 120 / 12 = 10:1
  2. Secondary current = 0.5 x 10 = 5 A
  3. Power = 120 x 0.5 = 60 VA
