A transformer connected to a $140$ V $($rms$)$ ac line is to supply $14\mathrm{.}0$ V $($rms$)$ to a portable electronic device. The load resistance in the secondary is $6\mathrm{.}00.$ What should the ratio of primary to secondary turns of the transformer be$?$ What rms current must the secondary supply? What average power is delivered to the load? What resistance connected directly across the source line $($which has a voltage of $140$ V$)$ would draw the same power as the transformer?
