Here I have a series LCR circuit with resonant frequency greater than 200Hz. Is there a way to know whether this circuit is an inductive or a capacitive load?

Edit: The only additional information we have is the phase shift between the inductor (with resistance r) and the resistor which is +45 degrees.

Here is the schematic:

enter image description here

Below are plotted voltages of the inductor (plot b) and the resistor (plot a.). The X-axis refers to the time with scale π/4 by division and Y-axis represents the voltage with scale 1V by division.

  • \$\begingroup\$ @Hilmar As mentioned the curve b refers to the inductor voltage and curve b refers to the resistor voltage. \$\endgroup\$

Yes. The circuit will have inductive reactance when the driving frequency is above the resonant frequency, and it will have capacitative reactance when the driving frequency is below the resonant frequency.
