To step 110 V ac down to 20 V ac, the turns ratio must be |
Answer» Vp/Vs = Np/Ns Vs = (Ns/Np)Vp We required turns ratio i.e., (Ns/Np) = Vs/Vp = 20/110 = 0.181818182 [Note: p - primary; s - secondary] For step down transfer, the turns ratio will be less than 1. For simulation: Step-Down Transformer Circuit Simulator. | |
