An LR circuit can be used as a "phase shifter." Assume that an "input"source voltage V=V_o*sin(wt+ Phi) is connected across a series combination of an inductor L=55mH and resistor R. The "output" of this circuit is taken across the resistor. If V_o=24V and f=175Hz, determine the value of R so that the output voltage V_R lags the input voltage V by 25 degrees. Compare (as a ratio) the peak output voltage with V_0.
