NARRATIVE
        Inductive reactance (XL) is directly proportional to the value of the inductor.

            Connect the apparatus to 110 VAC. Close the knife switch on the capacitor taking it out of the circuit. Turn the crank to lower the core over the inductor increasing its inductance. The light becomes dimmer as the inductance and inductive reactance increases.

            Resonance occurs in the RLC circuit when (XL) = (XC). Connect the apparatus to 110 VDC. Open the switch putting the capacitor in the circuit. As the inductor core is lowered, the bulb glows brightly at resonance.
