Problem $4$: Find the current in the line $($I line$),$ the power flowing out of the source, and turns ratio of the second transformer $($ N $),$ given that the power delivered to the load is $320$ W and the load resistance, shown as Rload, is $20$ for the following ideal transformer circuit. The circuit also has $R_s=5,R_{\text{l}\text{i}\text{n}\text{e}}=200,$ and the voltage source is providing $120V_{rms}$ at a frequency of $60$ Hz $.$ Assume that most of the power from the source is delivered to the load. $(15$ points$)$
