To step 110 V ac down to 20 V ac, the turns ratio must be-A-5.5B-18C-0.18D-0.018-C-0.18

Question

APTITUDE CRACK · Accepted Answer

C 0.18 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.
