Chapter , Problem 61(choose chapter or problem)
(II) An LR circuit can be used as a phase shifter. Assumethat an input source voltage V = V0 sin(2'irft + ) isconnected across a series combination of an inductorL = 55 mH and resistor R. The output of this circuit istaken across the resistor. I f V0 = 24 V and / = 175 Hz,determine the value of R so that the output voltage VR lagsthe input voltage V by 25. Compare (as a ratio) the peakoutput voltage with Vq .
