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 changes, if any, in the amplitude of the current in the circuit and the voltage across the circuit element. (Do not measure the Voltage and Current values to do this prelab!) Start.
What is the element in the circuit: a resistor, an inductor, or a capacitor?
