Weird Transformer Problem :(
"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?"
See attachment for Equation of Rs
I plugged in my values for the formula i got for Rs but got it wrong? I got 77.4 Ohms
Does anybody know what I'm doing wrong? Because i sure don't.
Any help will be greatly appreciated, thanks in advance!
