Problem

An ideal transformer operates with

1100\,\text{V}

rms applied to the primary and draws

0.50\,\text{A}

rms when supplying a purely resistive load on the secondary. The turns ratio is

N_p:N_s = 20:1

. The resistance of the load is closest to (a)

22\,\Omega

(b)

5.5\,\Omega

(c)

11\,\Omega

(d)

44\,\Omega
