## Homework Statement

[PLAIN]http://img192.imageshack.us/img192/8428/circuits.png [Broken]

## Homework Equations

[itex]\frac{V_L}{V_s} = \frac{nR_L}{n^2 R_s + R_L}[/itex]

[itex]R_s = \frac{R_L}{n^2}[/itex]

[itex]P = \frac{V_L^2}{R_L}[/itex]

## The Attempt at a Solution

How should I go about solving this problem? Do I have to convert it to an equivalent circuit? If so how would the end result look exactly? I haven't seen any good examples in the book of creating equivalent circuits of transformers so I'm a little unsure of what to do.
