In the AC circuit shown above, an unknown circuit element is connected to an AC voltage source. You can vary the frequency with the slide bar and see the graphical changes, if any, in the amplitude of the current in the circuit, the voltage across the circuit element, and the phase angle. (Do not measure the Voltage and Current values to do this prelab!) Start.
What is the unknown element in the circuit: a resistor, an inductor, or a capacitor?
