Question
An LR circuit can be used as a "phase shifter."
Assume that an "input" source voltage
V = V₁ sin(2πft + p) is connected across a
series combination of an inductor L = 52 mH and
resistor R. The "output" of this circuit is taken
across the resistor.
Part A
If V₁ = 34 V and f = 125 Hz, determine the value of R so that the output voltage VR lags the input
voltage V by 27
Express your answer using two significant figures.
