Problem

An ideal transformer operates with 1100 V1100\,\text{V} rms applied to the primary and draws 0.50 A0.50\,\text{A} rms when supplying a purely resistive load on the secondary. The turns ratio is Np:Ns=20:1N_p:N_s = 20:1. The resistance of the load is closest to a) 22 Ω22\,\Omega b) 5.5 Ω5.5\,\Omega c) 11 Ω11\,\Omega d) 44 Ω44\,\Omega
