a 500 omh resistor and a real inductor with a pure inductance L and an internal resistance of r are in series with a generator with a voltage of V = 10.0V and an angular frequency of w = 1000 rad/s. the voltage across the real inductor is measured to be at 4.73v, and the voltage across the 500 omh resistor is measured to be 6.57V. What are the values of L and r?
