• ID Code: K7-24
• Purpose: Demonstrate a series RLC circuit in a graphic way.
• Description: A series RLC circuit, shown in the diagram above, consists of a variable inductor, a fixed capacitor, and a light bulb serving as the resistor. The capacitor and the inductor can be removed from the circuit using parallel switches. When the capacitor is in the circuit, the inductance can be adjusted so that the bulb is brighter, dimmer, or the same intensity as when the capacitor is out of the circuit. The photograph above shows the inductance in its resonance position. The photographs above show what happens when the inductor is shorted out (left), the capacitor is shorted out (center), and both are shorted out (right), so that the bulb is simply wired across the 110VAC power source.
