**Weird Transformer Problem :(**

**1. Homework Statement**

"In the transformer shown in the figure below, the load resistance RL is 44.0 Ω. The turns ratio N1/N2 is 2.10, and the rms source voltage is ΔVS = 77.0 V. If a voltmeter across the load resistance measures an rms voltage of 26.5 V, what is the source resistance Rs?"

**2. Homework Equations**

See attachment for Equation of

**R**

_{s}

**3. The Attempt at a Solution**

I plugged in my values for the formula i got for

**R**but got it wrong? I got 77.4 Ohms

_{s}Does anybody know what i'm doing wrong? Because i sure don't.

Any help will be greatly appreciated, thanks in advance!
