RLC Circuits - AC Concept

Demonstrations in RLC Circuits - AC

Full LRC demo setup: wire spool inductor, LCR board with transparent component enclosures and light bulb on wooden base, function generator, and oscilloscope showing two sinusoidal traces

LRC Demonstrator

Demonstrate resonance in a series RLC circuit. Sweep frequency through resonance while the oscilloscope shows voltage and current becoming in-phase and current amplitude peaking when.

Fluorescent Lamp Circuit

A Sylvania demonstration board shows a fluorescent lamp circuit with visible starter and ballast components, and circuit paths traced in white and orange. The tube is half-coated with phosphor: the …
